It isn't that bad in my experience, type "disable iMessage" into Google and this is the first result: https://selfsolve.apple.com/deregister-imessage/ https://selfsolve.apple.com/deregister-imessage/ (which offers a way to deregister your phone number if you don't have an iPhone anymore). It definitely was bad when iMessage first launched, but they probably made that site five years ago and it works to get rid of it.
