Nothing Phone builds a blue bubble iMessage bridge while Google and Apple fight over RCS

Nah, Apple doesn't care.
These bridges like the ones found in Beeper/Matrix require a Mac server to perform the handshake with Apple's.
As long as these servers require Apple hardware to function Apple is making money.
It's roughly equivalent to running iMessage on your Mac at home and making an Android/PC app that remotely sends/receives messages to/from that iMessage app on your Mac.
