If any of the mods of those subreddits are here, can you reconsider permanently locking?
The communities on those subs took years to develop, and you're going to lose a lot of quality posts and discussion, since most people won't just move seamlessly to a new website. Beyond that, there are years of high quality posts that members of that community have made, which may not be utterly lost, but they will certainly be more inaccessible.
I'm pissed at the Reddit admins too, but I don't enjoy being forced onto some new site.
I'm writing with the context of the Twitter takeover by Elon Musk. I tried migrating to Mastodon (which seems analogous to Reddit/Lemmy). While I enjoyed not being on a site dominated by a person who, in addition to similar API price hikes, is racist and transphobic, many of the communities I value on Twitter never migrated. The result was that Mastodon was never an adequate replacement for the Twitter networks I was in. While I appreciate not giving money to a person I hate, I'm not eager to repeat that experience, especially because it seems like Reddit's breaches are more of a pure business decision, which I find somewhat palatable, even if I'm unhappy to be forced off the apps I previously used.
I definitely am not opposed to the existence of this website, and in time I imagine it may develop its own unique community that some people value more than Reddit. However, I enjoy having the option of both sites available.
