The number of Cardano pools must never decrease
Cardano has a huge number of pools that are managed by independent entities.

Cardano has a huge number of pools that are managed by independent entities.
Some operators operate multiple pools. Only 2 operators have an approximate 10% share in the production of blocks.
The third and other operators have less than a 4% share. There is currently debate in the Bitcoin community that 2 pools together have more than 51% share of block production.
Namely Foundry USA and Antpool.
According to some, this is reportedly not a threat to decentralization, as miners can supposedly delegate the hash rate elsewhere at any time. It's very dangerous not to see the tendency towards centralization as a problem, and to comfort ourselves with the argument that pool operators can't do anything without miners anyway.
