It's starting to look like we're getting more of a regulatory moat. (In the Warren Buffet sense of "moat", as barrier to competitors.)

An additional concern, at least in US tradition, is when once-again-centralized monopoly venues are being mandated (or given permission?) by politicians to censor or "curate" everyone's speech. I'm pretty sure I was taught in school that we consider that a bad idea here.

I generally favor a healthy amount of decentralization, that the remaining big guys be more common carrier (and stop claiming rights to people's communications), and a renewed individual sense of responsibility towards society (not gaming social media, playing to metrics, manipulating our lesser selves, etc.).
