Bots are fine in Singleplayer Mode how it used to be in BF2042 and previous titles, but filling regular servers with bots is just stupid and ruins the game. There should only be bots in Casual Breakthrough, but not in any of the main game modes like Conqest, Escalation etc. if you select that in the main menu.
I don't get bots in the main game modes in central europe, I really only get them if I play Casual Breakthrough, so it's also very much a regional problem. I think most game servers are in Germany and I live there, so I can't have any problems finding matches without bots. But it must suck for ppl that live in Australia or something.
