But it won't matter, because a mega corp scraping data is going to put it into their TOS and literally zero percent of these people are going to get off Twitter or Bluesky or whatever big website that has an exemption to whatever law is passed to stop the scraping of data.

The only groups who will suffer will be researchers, open source software builders, and pretty much anyone who isn't a corporation already.

There's no solution to this that will end with everyone being 100% happy, but keeping the open internet open and continuing this idea that has pretty much persisted from the beginning of the internet, that whatever you put out there is fair game for viewing, is ideal compared to the alternative.
