Without responding to anyone specific and only to put in my two-penny worth:
The only place where the logo was changed to a rainbow, was on Reddit. There, someone made a post which, based on solely the title, sounds fairly like a meme indeed. This was removed because of that reason.
When I go to the subreddit itself however, the top post is exactly about this subject: https://old.reddit.com/r/archlinux/comments/guvm7x/a_quick_thank_you_for_the_logo_change/
And even though the post is very positive, there are also many replies that are written by skeptical people who also think that Arch should not be involved with politics or statements in any way. And guess what, that's fine.
I wouldn't say that you are being censored and I think the amount of e-mails on this subject is unreasonable, considering the fact that the conversation is already ongoing on the platform about which you complain.
