Much more likely, it will only require firmware blobs on the actual wifi chips (not the general purpose CPU of the router/access point built around it) for compliance.
Which is already the status quo for 90% of all wifi hardware.
Which is already the status quo for 90% of all wifi hardware.
And they are killing the other 10%.
90+% of consumer PCs use a closed-source OS. Is it OK to ban the other <10%?
Without special licenses, it always was illegal to drive radio hardware out of spec. It was just largely a grey area because of how incredibly hard it was to enforce compliance.
While the hardware technically had shared-source firmware/drivers, you were never legally able to use it modified outside of specially shielded environments, so it's not "open" source in the true sense, and never was. Claiming that the FCC "is killing it" is a red herring, they're just enforcing laws that have been existing for longer than wifi.
Should the laws restricting radio broadcasting be abolished? Maybe. (Accidentally jamming radars or EMT/police radios can be a huge risk.) Maybe not. (If someone wants to jam EMT/police radio or radars on purpose, they can build a better contraption without using off-the-shelf wifi hardware.) But focusing on open versus closed software is a red herring.
