I think the last really big hurdle to an actually democratized internet is that we need to make it easier to host at home.
Asymmetrical download upload is such a fucking pain. I would rather have 100 down and 100 up then 400 down and 5 up like I currently do.
On top of that, there aren't a lot of good systems in place to enable me to host a website from home. If IPv6 were common it would be easy for me to secure a static IP address and to point that to my DNS resolver and attach my domain, but since I've got to be on an ipv4 system since no provider in my area provides an on-ramp to IPv6 and even if they did the Grand majority of Internet users cannot resolve IPv6 addresses, it's dead in the water.
If every person in America had symmetrical upload download and a static IPv6 address for their home, we could get rid of the grand majority of the content provider and hosts and instead use democratized systems like bluesky and Kbin and Mastodon and free tube without having to worry about these multi trillion dollar companies' bottom lines.
There are tools that allow people who buy ads to compare the performance of their ads with their own metrics.
The more ineffectual an ad platform is, the less likely ad purchasers are to purchase ads.
If 20% of American internet users used ad nauseam it would cause significant financial damage to ad companies across the globe.
