> if you liked the company or product so much why would you take shots like that?

Key word here is "liked". Seems like OP liked the company when it had a free tier, and no longer does after it axed the tier. They don't owe your company anything, in the same way your company doesn't owe anything to the non-paying "customers" it stopped subsidising. No foul play by either party. I wouldn't take it too personally.
