I think the mods should at least update the community's rules to justify their removal of some comments.
I recently asked about open source keyboards here. Some people mentioned a keyboard that (as far as I know) isn't open source, but it was mentioned a lot for some reason. There are a lot of comments removed by the moderation, I don't know if this is the best approach.
Maybe the mods should at least leave an explanation in the comments saying: "please do not recommend closed source software", so that users don't scratch their heads thinking "why are there 26 removed comments by the moderation?"
