Just because you can’t buy an ASIC Ant miner doesn’t mean that they have not developed one internally and are running a monopoly. (Spoiler: Bitmain already developed several ASIC miners for Cryptonight in the past)
Ethereum has it's EVM. Monero has it's RandomX algo to prevent ASICs, and it's Ring signatures to prevent tracing.
Some coins are pure Proof of Stake and try to solve scaling differently, see Algorand and Cardano.
There are altcoins that are just clones, referred to generally as shitcoins.
