not going to post in the glass thread but just my two cents: competition and enshittification can go hand in hand
pyrex for instance was once famous for making thermal resistant shatter resistant borosilicate glass cookware, however as time went on they switched to more fragile tempered glass
however it is very easy to buy no brand store brand borosilicate glass cookware nowadays which is just as good and affordable as well; it’s just people who still buy pyrex who get shafted cause they expect the quality of old but are actually getting an inferior product to your generic store brand
