What trust did they break exactly? Genuinely naive here. Did they woefully underdeliver on their cloud offering's promises?

Some amount of customers bought into the cloud offerings, which are now being sunset. Meaning those customers now have a forced migration to something else. Will they now trust the company and pay for enterprise licenses (and figure out how to host it), or is there enough distrust that they migrate to something else like AWS RDS/Mysql?

Ah, I misinterpreted the top comment, then. I thought this was a strategic move on their part to salvage trust elsewhere.

You're right; this is like pulling the rug out from under guests you invited into your home and telling them to seek shelter elsewhere.
