No, there are all sorts of ways we can end up liable for stuff too.
And even ignoring legal issues, what are we supposed to do if somebody posts a political comment (that fits the context, e.g. explaining more detail about how a particular politically-charged term is used somewhere) and authorities in some jurisdiction flag it + tell us to take it down? Do we give in to them and have people call us fascist stooges, or do we not give in and possibly have our entire app banned there?
I could imagine us adding a feature someday to pull in data from a user-selected set of feeds - there's no reason you couldn't have a Fediverse protocol for "adding commentary on generic/universal topics" (in fact that would be a pretty interesting idea for a lot of reasons), say - but I'm extremely reluctant to have something like this officially hosted by Pleco.
