I feel like the whole time this was being argued and passed, everyone in power just considered the internet to be the major social media sites and never considered that a single person or smaller group will run a site.
IMO I think that you're going to get two groups of poeple emerge from this. One group will just shut down their sites to avoid running a fowl of the rules and the other group will go the "go fuck yourself" route and continue to host anonymously.
Does this shock you? I don't recall a time in memory where a politician discussing technology was at best, cringe and at worst, completely incompetent and factually wrong.
So? Tons of millennials barely understand technology too. I'd say a politician being one makes the odds they know tech marginally better, but I still interact with people of my generation that barely know what a filesystem is, let alone how to make one, or why it's important.
