We can fairly reasonably assume whoever is telling the truth is doing so about both things. Signal should know whether or not their payment details were actually having issues or not.

Now, if you want, you can believe that Signal is lying about whether or not the ads were rejected, wrote an extremely misleading blog post that strongly implies the suspension was permanent when it was temporary, but has correctly guessed that the real reason for the (temporary) suspension was their (unsubmitted) ads, and that they wrote this blog post rather than trying to submit their ads for the first time after being unsuspended.

But at that point, I would say that you are "presupposing because you're coming to a conclusion that is not justified by the evidence". You are so strongly biased that Facebook must 100% prove their innocence on every single point, but are just automatically assuming Signal is telling the truth with no evidence.
