And I don't see why publishing a public key file to a key server should trigger any special semantics regarding email encryption without an explicit "I currently have this key accessible, go ahead and encrypt email to me using it" flag.
Because that's what a public keyserver is for. It's not a private file syncing service. You can use it as one, but don't get mad at others when they use public keyservers as intended.
> Although OpenPGP’s main purpose is end-to-end encrypted email communication, it is also utilized for encrypted messaging and other use cases such as password managers.
Tools and protocols evolve. Just because it was generated with email in mind doesn't mean that that's what people use it for these days.
Yes, but that still doesn't grant you permission to yell at people using it as originally intended. And whatever the "modern" usage for PGP may be, the purpose of keyservers still remain the same: publishing keys for others to use, or discovering them.
