I find it difficult to believe it was a bug. Since they use HubSpot, they'd need to call the HubSpot API to make it happen, which strongly suggests intentionality to me. To be fair, they seem to understand the severity of the issue and are acting appropriately.

I find it particularly disappointing because I've been burned a couple times by their use of the annual/monthly pricing dark pattern (accidentally purchasing a full year subscription based on displayed single-month-only price). I don't think two instances of unfortunate functional behavior is necessarily indicative of the entire business, but it's seriously making me consider alternatives.

This is super unfortunate if true. Sounds like Michael Bloomberg is getting hands-on, which I can't imagine Josh would enjoy.
