It also sounds great until you consider other countries. Most people on Twitter are not in the US.
The US has more than 30% of its population on there, the third highest- India has about 20 million of its 1 billion+ people.
From my small Eastern European country - no one I know uses Twitter, Reddit is more popular than it. That’s anecdotal, of course.
It says there are 206 million active Twitter users, 77 million of them in the USA. That’s less than half of them.
Of my family and friends I only know of 2 who use it actively though most have an account.
Musk's Twitter is certainly going to clash hard with Europe's recently adopted Digital Services Act.
It's easy to point to 'oppressive' countries like China (where twitter is banned), or Turkey[1], or India[2] as examples of where speech can be severely limited, but there are many limitations to speech in other countries like Germany, Canada, France, Australia, UK.
When you make a globally available website, how do you "follow the law" when the laws of various countries are not compatible with each other? Do you geolock all tweets - Canada twitter is vastly different to US twitter? That doesn't sound scalable good!
