Giving conflicting informations to people all around the world expected to interact with each other is a bigger issue.
Also burned a couple of people as witches in the process...

I agree with this, but consider the drawbacks to rampant disinformation and the proliferation of deepfakes (all this is IMO): it will make any video or audio deniable and unusable as evidence. Real images will be denounced as fakes. Fake images will catch on and possibly cause real damage. People will rapidly lose trust in most sources of news, entrenching established known quantities.
I feel like if we could reasonably put a stop to this we should. I don't think we can in general, though.
