@Matty_OW Perhaps the first question you should ask is what the other party really wants out of an interaction. In this whole feud it's pretty clear it's to solicit a reaction, and by the looks of it they've elicited a multi course Michelin starred meal.
@Matty_OW You don't need to justify being cautious about anything in life. If you stop questioning things you throw away your autonomy and will go through life autopiloted by the people/organisations you interact with.
