There is a difference between a general scare about the AI buzzword and legitimate distrust in online services which are closely connected to american spying institutions (regardless if they are ai or not)
If my calories tracker app would apoint a (former) NSA official on their board, I would be looking for alternatives too. This is not about AI, this is about a company with huge sets of private data being closely interconnected with american spy institutions.
Sad that you don't seem to be able to distinguished between legitimate security questions and badly informed hypes/scares ass soon as a buzzword like AI occurs
