No kidding
"large tech companies 'enjoy a remarkable degree of freedom from regulation and accountability for their activities and the content they carry' "
Yup. And, in my opinion, it's because the Internet has never been considered as something important by governments across the world.
But that is changing. All you need to do is look at how many governments have officials with their personal social media page when they should be talking through official government channels. Or look at how many governments actively control, at sometimes forbid, Internet activity. Oh sure, the ones that do that now cannot be counted as democracies, but the day is coming when Internet regulations will be decided upon and enforced.
