It's disappointing to see some of the larger subreddits going public with a 'what's the point?' tone. Most are staying private, but some aren't. As if Reddit doesn't exist solely because of its user generated content. If enough subs permanently shut down they'll have to reconsider their API position.

I decided to write a letter contacting the subreddits I've been lurking for years saying how vitally important it is for subreddits to protest right now, at this critical time, before it's too late. I've politely implored them to continue the protest saying how these API changes with have a long-lasting, permanent impact on Reddit as a platform for the worse. I'd suggest you guys come up with your own letter template and message the mods of those subreddits in polite form. It'd be great if we can convince these exceptions to go private again.

I used Reddark to determine which subreddits to contact. I'd say only contact hobbyist ones such as sports rather than more politically-inclined ones like Ukraine that have a fair reason to stay open. Also some subreddits have made poll posts asking their users if they should go private like Gaming and NotTheOnion, so please don't message those ones.
