Louis C.K. strikes me as a guy with better things to do with his time.

Besides, the people having issues with PayPal have (almost?) always been using terminology implying that they were taking donations without being registered as a non-profit, or were taking money with the promise of a return in the future.

I'm not trying to defend PayPal here; I'm just pointing out that there is specific behaviour that is likely to invoke their wrath, and Louis C.K. does not appear to be doing those sorts of things.
