As a more serious aside to the above, it is generally worth paying a bit of attention to which instance other users you interact with. There’s obviously no blanket statement you can make about the users of particular instances, but there are definitely certain instances that are more appealing to… certain groups of users.
lemmy.ml in particular has a bit of a reputation for having tankies on it, but there’s lots of very interesting and reasonable people there (or here, I suppose, given this is an ml community), also.
What point are you trying to make?
That there’s better FOSS software (just generally)?
That there’s better FOSS document editing software?
That you don’t like Libreoffice dark mode?
It looks pretty good to me
