Never trust any company with a PR department at all, they're all opportunistic liars who's priority is limited damage to the company, not telling the truth. They only do the latter when they think it will have the effect of the former.

Really, don't trust corporations at all. Even if the circumstances of life force you to do business with them and hope nothing goes wrong, that's no reason to ever trust them. The bigger the corporation the more true this is, since the structure of corporations makes people feel less personally responsible for the bad things they might do to you, like lying to you about the scope of a data breach. The "just following orders" mentality allows workers to do things they'd never otherwise do to you, and that's just one example.

If any sort of business is safe to trust, it's the one-man-shop owner-operator kind of business and you can only trust those guys insofar as you can trust any other person at all. In that case you have to consider it on a case-by-case basis.
