I don't think that's how most business relationships work. When I buy a high end sintering 3d printer, for instance, it doesn't come with a mountain of consumer protections because it's assumed that if I'm buying one, I know what I'm doing and will make sure the purchase contract contains warranty clauses, support, and so on. The cheap FDM 3d printer I bought off of Amazon, however, is targeted at Joe Public and thus treated differently by the law with a mandated one year warranty.
I'm not sure what the legal test is for differentiating the two, but the difference is definitely recognized by the courts. IANAL but it's unlikely that the courts would decide that app developers are consumers in the classical sense.
That said, it doesn't matter (again, IANAL). Consumers are still being harmed, as Apple so graciously showed by removing Epic from the store - removing consumer choice in a free market is anti-competitive.
