The two main devs seem to be Tankies or have at least close views. From what I heard, the hardcoded filter isn’t a thing anymore and was removed after heavy protest from other contributors. The good thing is that they don’t have any control outside their own instance and in worst case people would simply copy the project (since it’s open source) and move on without them. I hope that the different instances + community take a part of the donations to pay independent full time code contributors.

In addition to the more important issues that fedi-tips discusses I find their stance on anti-vax and US-election conspiracy theories… unappealing, which you can see being discussed here: https://lemmy.ml/post/143057

And that they haven’t been shy about exerting their power for political purposes. The hardcoded slur-filter was explicitly about discouraging “right wingers” (I put that in quotes because I suspect their definition of right wing and mine differ), and they at least use to be open about their intentions to moderate the instances that they run as explicitly “left wing” (though I don’t see a reference to that on the current site).
