It's clickbait. The "driver" is actually a rather comprehensive kernel patch that modifies existing GPLv2 kernel code, so by its very nature it is at least GPLv2 (original parts may be dual licensed by the vendor if they want to, but they can't not make it GPLv2).

What this person paid $40,000 for is access to development kits for certain hardware, which with chip vendors like that usually also comes with support. The vendor cannot prevent you from exercising your GPLv2 rights after they hand you the code. In fact, if you manufacture and distribute a device that uses these kernel patches it becomes your obligation to enable your customers to exercise their GPLv2 rights. Chip manufacturers know this and (if they are somewhat reputable) usually license their code appropriately.
