Too late to be worrying about that now. The glass change was quite a while back.

I'm of a certain age that my pyrex is from a while back

I assure you this bankruptcy won't affect your existing Pyrex.

Well, you can keep using it after the company went bankrupt.

Until they disable the licensing server so the next time it needs to renew the license it fails and becomes unusable. So glad I bought that smart home pyrex set of dishes
