If enough people don't like the changes in an open source system, they can get together and fix it or fork it. I see a number of others comments mentioning the already working (non web3) solution Mastodon - and that's a great example of this in practice. To look at it another way, how would web3 actually help here? As far as I can tell it would only make this example worse - a more user hostile UI (faffing around with wallets and keys and whatnot), less decentralised (everything going through one API to interact with the blockchain), more resistant to change (forking blockchains is a big deal and only tends to happen when rich people at the top of the pyramid don't like something), more expensive (gas fees), less privacy (your wallet address being essentially an undeletable cookie), more likely to incentivise divisiveness and conflict (flamewars driven by the expectation of personal profit rather than just likes), etc. etc.
