If people cared about decentralization then we would not have seen the consolidation that we've seen. That's true even for technologies who pitch decentralization as a core feature, as we saw with cryptocurrencies -- the original argument was that cryptocurrencies allowed a decentralization of finance, but then we saw a handful of platforms centralize the trades, and most people who bought cryptocurrencies were pleased to have this convenience.

From moxie.org:

"Given the history of why web1 became web2, what seems strange to me about web3 is that technologies like ethereum have been built with many of the same implicit trappings as web1. To make these technologies usable, the space is consolidating around… platforms. Again. People who will run servers for you, and iterate on the new functionality that emerges. Infura, OpenSea, Coinbase, Etherscan."

They also make this point:

"I think this is very similar to the situation with email. I can run my own mail server, but it doesn’t functionally matter for privacy, censorship resistance, or control – because GMail is going to be on the other end of every email that I send or receive anyway."

For a variety of reasons, people have not felt that it is worthwhile to fight for decentralization.
