There was no "evil" or "dark" stuff going on. If the Acolyte was written with the coven as the heros you would see that it's the Jedi who are intrusive, demanding and use the dark side of the Force. It's just the point of view. A light sabre is evil if you're on the wrong end of it.

I don't know why this is a big deal. The Jedi are wrong. Again. Their position is that only Jedi can train you in The Force, but there are other ways. The Witches are a females based Force sensitives, and the covens are not necessarily linked.

Mistake 1, Nightsisters don't raise younglings. Well obviously they can and do when they need to.

Mistake 2, the Jedi have the right to test children. Do they? Really?

Mistake 3, there's an age limit to training. Isn't it dangerous to leave untrained force sensitives around the galaxy, if found, just because of an arbitrary rule?

Mistake 4, younglings must give up their family connections. The Jedi do, but the witches don't, in fact they reinforce the communal connection.

Mistake 5, Jedi can't marry. Well, we know how that turned out.
