this is basically the "computer scientist" view of the world in https://ansuz.sooke.bc.ca/entry/23, especially the Monolith bit. spoofing UA could be legal in general or when done for interoperability but illegal when done with intent to bypass access control.

Well the UA spoofing I perform is done to bypass sites not wanting to serve me content.
