Do you really believe that as long as Christ is preached it’s necessarily a ‘good thing’?
Christ can be ‘preached’ in a lot of different ways.
(When I first arrived on the scene here, I was called all kinds of names because of the interpretation to which I adhere.)
There are two core doctrines to which Christianity adheres. Who God is and what is his plan of salvation. If you get those two things right, then yes. You can have all manner of misinterpretations and heretical beliefs but you you get those two right and you’re still considered Christian.
If you get either of those two wrong, you tend to get labeled as a cult. But cults tend to get both wrong. They usually demote Jesus from being God and add their own conditions to the plan of salvation.
