Yes, it's odd to me that everyone has to serve some random JS from some random ( to me very untrusted) third party cdn server. Why every single random site has to have like 8 different domains with random character variations and serve javascript from it. To me that seems completely bonkers, absolutely unstrustworthy and extremely lame, as if they have no actual money to do it like a normal person. Like FB serving stuff from facebook dor com but also from random, lame domain fbcdn AND also fbsbx (wtf is that???!?, i dont trust it at all). And thats on the "reasonable side", random wordpress site or eshop is a complete nightmare in this regard.
