I'm surprised so many replies here are about removing a free tier 2 years ago. Things cost money, what did you expect? Whenever I get free products that cost money I expect it's either temporary, or I'm being the product myself.

I do think it was a little bad move because now you can't even test planetscale and the memories of its free stuff still might haunt some people
I didn't enjoy doing it. I felt bad but I don't regret it at all.
Sure, it sounds like a marketing mistake, and you're owning up to it not being sustainable.
But you're burning trust with people before they even have a relationship with your company if you pretend it never happened.
It's much better to say "Sorry non-customers, this wasn't sustainable. I hope this new approach will better serve us both in the hobby use case and still be sustainable!"
