Cheats should always be enabled on servers and removed from multiplayer filters and server pages.

Cheats are only cheats in single player, on a server they’re admin tools, that when disabled, limit the Admin’s abilities.

Since server commands need a permission to be executed by the players, having a filter for servers with cheats may mislead them into thinking they can execute them when joining.

The argument that they're admin tools is reasonable. I think that depends whether the admins are using them as tools (e.g., spawning an item to replace one lost in an unfun or unfair way) versus using them as cheats (spawning in end-game loot for themselves).

The cheats filter has certainly be controversial. After a recent update it defaults to "any."
