Ask HN: How long will existing users get original Hasura prices?

Wasn't sure where to ask this, so here I am.

Hasura recently upped their cloud prices big time, to the point where if I had to pay the current prices, I wouldn't be using the service.

The prices only apply to new projects it seems, but I'm obviously concerned about my existing ones.

Are there any precedents for companies staying true to old pricing models?

I'm wondering whether to begin the migration away from Hasura, or to rest assured that my pricing will never change. I'd prefer not to be doing a hectic migration on some kind of deadline.

Thanks!
