Except, legally in the US where Valve is based, you've got 0 legs to stand on.
Valve does dominate the market they're in, but they do so without creating an unreasonable restraint of competition in that market. They are dominant by providing the best product, not because they have unfair business practices which burden the competition. Like I said, Valve will literally allow game makers to go and take 100% of every sale they make (assuming they can process payments for free) while still allowing them to use the platform Valve have built and pay to maintain so long as they'll pay Valve a cut for the copies that are sold directly through the Steam store. Valve allows their competition to sell games that package said competition's stores inside of those games. Every EA or Ubisoft game comes with the competitor's store bundled in. They create tools that allow their competitors games to run on platforms that the competition doesn't want to bother with and they give them away. HOW IS ANY OF THAT AN UNREASONABLE RESTRAINT ON COMPETITION?
"Here you go guys, you so obviously don't understand what the audience wants. How about you give us a cut of the sales you make on your games via our platform and we'll let you install your platform on our customer's PCs? How unreasonable and diabolical of us to cut down the competition by letting gamers see what an open sewage pipe of fetid scum they'd be dealing with in our absence. BWAH HA HAH HAH! We have constrained the competition by our cunning craft of having a better product. Truly we are monsters from HELL! HAIL GABEN!" -Valve, The monopolists 🙄
Steam is the antithesis of anticompetitive, they're not the single seller of any good beyond "Valve Games" of which there are now 22(?) among millions of PC games, and they don't generally dictate prices in the market; which is the succinct way of saying that they don't live up to any portion of the legal standard for what constitutes a monopoly. Give me something factual that implicates Valve as a monopoly or get out of here with this nonsense.
First things first, you cherry picked the one thing from my link that supports your position intentionally ignoring that it is a single prong in a standard that has several. Second, I'm glad you brought the FTC link, because they also do not agree with your stance if you bring the whole context from your own link into the conversation:
Your definition only meets one portion of the FTC standard, which is why my comment addressed how Valve fails to meet any of the points of the standard beyond the dominant market position. YES STEAM IS MARKET DOMINANT, BUT NO THEY ARE NOT A MONOPOLY BECAUSE THEY DON'T MEET ANY OTHER PORTION OF THE STANDARD.
To do what? PC is an open platform that they don't control.
To make people raise prices or exclude competitors? Again, how or where?
Epic is LITERALLY excluding competitors right now for a bunch of titles, other competitors have done likewise until they recognized that customers didn't like it and decided that it wasn't in their best interest to do so.
Not to beat a dead horse, but how? They literally have no control over PC users beyond that which they've earned from being the best of MANY options, so how could they possibly parlay that into a power they could use to exert force over consumers or developers? Unless they did something that made them into not the best option, they have competition from every angle including from their direct competitors at Microsoft whose platform (as of March 2024) houses 96.67% of their customers with Windows being the dominant OS for Steam users by an absurd amount. There's incredible danger for Steam to try and pull anything anti-competitive because they literally live in the house that their competition built.
You seem to imply that Steam being a monopoly has caused Remedy to suffer poor sales. However, we have the following problems there:
A) Steam fails to meet the legal definition of a monopoly. Just full stop. You attempt to take singular statements from a legal concept that by design has multiple prongs (specifically because we do not choose to harm companies who do no competitive wrong and come to their dominant position through the art of their craft being superior), but that's just willfully misunderstanding the concept of a monopoly.
and
B) A developer choosing to launch their game on the Evercade Vs and failing to see the sorts of sales numbers they might expect on Sony Playstation/Microsoft Xbox/Nintendo Switch is hardly a justification to claim that the game did poorly because Sony/Microsoft/Nintendo are a oligopoly. The dev CHOSE to launch on a shittier platform, one that doesn't offer all the things that the current market expects. The devs are going to see lesser sales as a result, that's just how it works, they weren't harmed by a monopoly effect, they were harmed by their poor market choices.
See, I think your problem may be that you think market share aside, all other things are equal, which is simply not the case. By your logic I should be able to offer you a nice shiny and new Evercade Vs in exchange for your Playstation 5 because it's only the market share that makes it so that the Evercade has less games to play? It's only natural where Steam is bringing more to the table, it has more customers as a result. EGS offers a pale shadow of what a consumer gets from Steam, so why should they count as much? Who owes them that? They need to get on that level if they want that credit due. They currently matter about as much as the effort they're putting into competing, which I'll agree isn't much, but is hardly relevant here.
