>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!"
