Seems like they (A) are killing the free tier and forcing active users to upgrade to paid plans; and (B) screwed up and also sent out emails to users who have been inactive and had their accounts deactivated (thus accounting for the flood of angry people who have gotten demand letters for a site that's throwing 500 errors for them).

So, total fuckup on their part. While it's not out of bounds for them to phase out the free tier, doing so with basically no notice to those active users, and then also accidentally spamming the (at a guess) 95+% of users who once signed up for FogBugz and then never touched it again ... not great, Bob. Not great. Hope their acquisition price didn't assume the ability to convert those free tier users to paid, because I doubt many are willing to stick around given the way this was handled.
