P4 is used by Cisco Silicon One, Xsight, AMD Pensando, Intel Mount Evans, etc. "Contact us" isn't the same thing as vaporware; the Pensando SSDK and Intel ES2K SDE definitely exist for example. I realize it sucks when things aren't available to hobbyists but it's a mistake to pretend it's fake. P4 is really only needed in data center networks because slower campus/home networks can usually get away with software processing and their lower prices probably can't support the R&D of a programmable architecture.
