Sync and maybe some other apps already put ads next to posts. Ironically this post specifically had an ad next to it.
As for bargaining power, bargaining for what? Ad revenue? Are you serious? No thank you, you’re asking for reddit but worse. You’ll get ad farmers submitting garbage content overnight. I know Facebook is going to profit off my *waves hand* fucking everything. That’s the price I pay for participating in an open system. That’s the state of the internet right now. Everything gets monetized by everyone except you. If you don’t like it, disconnect. There are literally trillions of dollars against you, any action you take will only make it worse for everyone else, because these companies have the money to force judgements in their favor.
Welcome to life. It fucking sucks here.
Edit: an analogy I thought of would be this: you’re talking loudly in a small, private park that has no fence. The only thing that indicates that it’s privately owned is a little sign that says, “Property of Lemmy.world”. Anyone passing by on the street can overhear your conversation. Someone decides to set up a viewing platform on the street where they charge money for people to come and gawk at you from the viewing platform. There’s absolutely nothing illegal about doing that. There’s nothing illegal about someone taking notes on what they overheard. There’s nothing illegal about someone selling their notes either. Because they aren’t officially entering the park, there’s no TOS for them to sign, nor an Eula that binds them. Your trying to impose restrictions on someone outside of the park’s jurisdiction. Sometimes, people are successful at doing that, but generally it comes at the detriment of everyone else’s experience.
There is some federation, however most instances that I’ve seen are people’s personal instances because in the past you’ve still needed a bluesky invite to federate with the main instance. Now that you don’t need an invite anymore I’m sure that’ll change and you’ll see more public 3rd party instances popping up.
