I think what they're saying is that you have to go back 25 years to get true Corning Pyrex. If your Pyrex was 25 years old, you'd be safe. It would only explode if it was less than 25 years old.
Well, that's just lovely (not). It doesn't say how long before those micro-cracks develop. Maybe it's a combination of time and usage. I don't use mine daily, but I do use it at least a few times a month. I don't know how old my stuff is, either, because some things have been replaced for various reasons. So one piece might be 3 years old and another piece might be 15 years old.
What to do? I guess I'll risk it. What else is there? I bet Anchor Hocking is the same material. The frequency of it exploding is obviously rare, or it would all have been recalled - though I'm surprised it hasn't been.
