TP-Link agrees to allow third-party firmware in FCC settlement

FCC doesn't want consumers to be able to fiddle with their hardware and it's up to the hardware manufacturers to cover the cost to enforce it if they want to be able to legally sell these devices.

Sometimes they care just about frequency and power, sometimes they care about a lot more then that. Depends on the device being sold.

I am much less concerned about 'OS-evangelism' and actual Freedom for people to innovate and move the technology forward as well as having the ability to protect oneself from the negative aspects of technology.
