That's the majority of actual chains in the top 20, since many of the rest are tokens running on top of other chains (USDT, USDC, SHIB, BUSD, &c)
In general, starting a clone of proof-of-stake Ethereum is a very popular way to make a new chain.
As for the philosophical point, PoW isn't really different. It takes tremendous capital investment to produce enough hash rate to ever mine a BTC. These are all more or less systems in which the rich get richer and the not-rich get to gamble.
