And I guess this is sort of how fediverse is working.
Protocols don’t make much money compared to walled gardens selling max data possible.
They could still try! But you'd have options.
Take email, for example. I cannot imagine something like that coming into existence today.
I can use my own client to avoid ads and tracking from my service provider—did I download this message? Sure, the server knows that. How long have I looked at the message? Which message did I look at next? Did I follow any links (yes, someone might track that part, but my email provider's going to have a hard time doing that)? What mouse movements did I make while looking at it? No such luck there, and yes websites and closed-platform services do track that stuff.
I can switch providers. Say my email provider starts injecting trackers into all links. I can just dump their ass if I don't like it. I keep using email, and now they receive zero info about me (I mean, they might get a little if I send emails to their users, but you get my point). If I have my own domain name I don't even need to tell anyone I switched.
I can email someone using a different provider. Yes blocklists or whatever might cause a problem but, fundamentally, this does work.
Protocols force providers to act like a telco, at least, except that the situation's even better for software because the barriers to entry in the market are so low... unless all your competitors are giving away access to their strictly closed ecosystem for free, and not supporting open protocols. Then you're screwed, and that's exactly what's happening now and why the Internet protocols are largely frozen in time.
Because in my opinion the browsers would need to make it as easy to use as any other website or phone app if it were ever to gain traction.
Yes yes, there's radicalization for everyone! God forbid you want to use social media for something besides political fighting though
The Federated Timeline is slightly cursed (I haven't curated it for a while), but less so than Twitter. (My instance, Fosstodon, doesn't really federate with the Nazi instances; those it has ended up federating with have been swiftly blocked, because Fosstodon's admins don't like admin-condoned harassment of their users.)
And I'm glad that with email we don't have server operators deciding on politics for their users. ActivityPub has a long way to go if labeling instances as "Nazi" is enough break federation.
