I think there are also good projects in blockchain that and web3 that are not bitcoin. Ofc we also have a lot of scams but calling everything that is not bitcoin a shit seems a bit radical. And afaik every one sided radical point of view is wrong

If you get known with Bitcoin and its layer possibilities in quite deep manner then you will understand why Bitcoiners say that "web3" is just a scam which can be done easily (and way better) by a company with a centralized server solution. Words from their mouth like: "Web3", "DeFi" etc. it's just Fugazi.
