You yourself say that "the increase from 2% to 30% is way more questionable". What is "questionable" about that? Maybe that is not stealing but it is an obvious fraud.
I really don't get what your motivation could be to defend that kind of shit.
The plugin author claims that the ramp-up to 30% is an anti-abuse measure. Supposedly, something triggered the abuse abuse flag and the rev-share ramped up as a "get in touch with us" signal, with the additional rev-share refunded when the user does get in touch.
Taken at face value, I think that's not unreasonable, though the lack of logging from the plug-in author's side is questionable (asking the customer how much they wanted refunded).
Where I think the jury is out is whether that is actually what happened, or whether the plug-in just ramps up every customer to see what their pain tolerance is.
