I mean,
I still feel that a dev willing to take a lost sale over a resale, still says more than just saying they're misinformed.
And at the end of the day, resell is supposed to be a cheaper way to say "I bought it". And at the end of the day, devs are saying "If anything, it's worse for us"
I don't think it's ridiculous. I think resellers are more needing to prove their legitimacy in this case.
The thing I find most ridiculous honestly, is that you seem to be under the assumption that the devs aren't already getting noisy chargebacks. Like this whole thing sprouted from nothing.
