It’s probably not “average developer” either but some of the big box software still has per-socket licensing, or had until recently anyway.
CPU as in core or socket? These days most CPUs are "many-CPU-cores-in-1-socket" and having X CPU cores over 1 or 2 sockets make a small difference, but software does not care about sockets.
Plenty of enterprise software is licensed on a per-socket basis.
And if they read this press release they will probably try to switch to per-core licensing.
