They might not be doing it on purpose, remember that microsoft windows "take a screenshot every few seconds and send it to an llm" thing?

Be angry then, IM communication is not a contract with terms unilaterly decided by one party. Or put a confidential signature with every message, see how well that works for you

Be a better person. Or at least put a message in your status that you record everything and send it to Google for analysis for minimum personal gain. Do you also carry a second phone to take a photo just in case someone sends you a disappearing photo?

google? signal desktop is not on android, is it? no, its on a pc, as could be a local llm. did i even say i did this before you wanted to assume that you are a better person because what your preferences should be universally obeyed?

If I need a contract for you to treat me decently and respect my choices, I really dont think you can count as a "friend" at all.

naively assuming everyone will do whatever you want is closer to delusions of grandeur than ethics.
