It shouldn’t / probably doesn’t. It’s not obvious what the justification is.
What is obvious, is that Envato is passing along the cost of doing business to their customers… right in their face! If you have to cover cost of doing business, at least do it in a smart way that customers aren’t going to leave your platform altogether when they see it!
There is no way everyone is on board with these decisions internally over there… I have only been around a couple years but this is the only time I’ve seen an entire thread more or less completely agree including both authors and customers!
