That only works if you assume that Meta is lying about the E2EE. But earlier you took this very event as evidence of that fact, hence it seems you're begging the question.

Someone else has pointed out that it isn't legal to offer E2EE services in the UAE and so Meta intentionally compromises it in that market one way or another. They don't seem to be hiding that fact though so it's hardly an elephant.

polity - a political organization

politely - courteous, socially correct, or refined manner
