You'd be surprised how much stuff is made on these old processes. A lot of very security-cricial stuff like Baseboard Management Controllers, lights-out management controllers, and laptop embedded controllers are almost entirely built on pre-OPC (i.e. pre-90nm) processes. All of those chips are in the "security flaw equals remote root" category. SkyWater's 130nm process is compatible with on-die flash (unlike most post-90nm and nearly all post-40nm processes). You could do a "secure enclave" or your own Hardware Security Module and not have to worry about backdoors. But to answer your question directly: this isn't about making an iPhone comeptitor.
