Having gone through this multiple times on both Mastodon and other social networks (Google+),
not having a readily-accessible discussion record is a problem.
I'd created both a subreddit (https://old.reddit.com/r/plexodus) and wiki (https://social.antefriguserat.de/index.php/Main_Page) to memorialise at least some of that discussion, as well as the on-platform discussion.
That last is of course now unobtainable, though there were over 700 snapshots of the community homepage saved to the Internet Archive's Wayback Machine, see:
<https://web.archive.org/web/20190401071102/https://plus.goog...>
Because of the mechanics of both G+ and IAWBM, actually navigating to articles from that archive ... mostly does not work.
The G+ community had over 4,000 members (pretty good for late-stage G+). The subreddit ... a hair over 300.
People. Will. Not. Go. Off. Platform. Even. If. That. Completely. Fucks. Them. Over.
It's a really perverse dynamic.
