I don't really have a position on the issue one way or the other, but it is insane how quickly this somewhat small issue (compared to stuff that everyone has been talking about for decades, like abortion) became part of the culture war, I already see "come and take it" memes being made.
in 1998 pyrex stopped using borosilicate glass and used regular soda-lime glass (in amerika, in europe and other places pyrex is still borosilicate). modern amerikan pyrex is no more resistant to heating than any old glass bottle. of course, labs still get the real stuff
