I agree with your sentiment, but do any of those package managers prevent some random repository from adding Firefox version 190 which will install on next apt

I agree with your sentiment, but do any of those package managers prevent some random repository from adding Firefox version 190 which will install on next apt upgrade? Not that they need to - presumably any package I’ve installed already basically has root access.

Yes. Apt has preferences and pinning. Basically the official repositories by default have higher priority than other repositories. You can change the defaults, but you'll know when it happens (because you have to do it yourself).
