I can see this having an impact on news organizations embedding Tweets in their stories. They'd be more hesitant to do it if they knew that a majority of readers would see an error or a log in form.
The steps Elon has been taking make it seem more like his takeover of the platform was part of a concerted effort to just destroy Twitter and remove it as a force on the internet that needs to be taken at all seriously. I wonder if he's backed by the US government. I'm thinking about how much impact Twitter has had on politics and elections and the mostly negative impact it has had on US society and culture lately.
Either way, I deleted my Twitter account about a week ago after being on there for 14 years. I already don't miss it.
