I'm still not fully convinced that Unity's new pricing is unfair. The retroactive aspect of it is certainly troubling and I've seen some fair points about how policy implementation will likely be messy. Moving onto the pricing itself, I've only seen it brought up on a couple occasions that the actual stores these games are being sold on are taking a way larger cut in most cases then what Unity is asking for (For reference, Steam, Apple, and Playstation: 30%, Google: 15%, Epic and XBox: 12% -- please correct me if I'm wrong about any of these).
The flat pricing model will disproportionately effect cheap mobile games, which I suspect was on purpose. Even then, I hardly see this as a problem. Just scrolling through the top games on any mobile store, most of it looks like low quality crap produced by large companies that figured out a successful formula for virile games. The only empathetic party I can figure in this mess is indie mobile game developers, which seems like a pretty small category of Unity users, certainly not commensurate to all the huff people are making.
