This doesn’t necessarily mean they’re not being impartial.

If a side’s position is the truth, they’re going to support impartiality, because they want the truth to be spread, which supports their side.

My only question is whether they’ll allow progressive types on their platform long-term.

I feel like every platform outside of the Fediverse is like this nowadays.

From what I saw they are impartial but have an enormous moderation problem. Most likely due to being overwhelmed by the influx of new users.
