Your Wifi card in your PC is a locked down certified device.
What they want to solve?
Radio is a shared medium and everybody has to follow the rules. Especially there are parts of the spectrum used by so-called first user like weather radar, military use, and alike. Originally radio was seen and considered as an somehow unlimited resource like IPv4 addresses. But then this this unlimited resource became very limited like IPv4 addresses. So now, we have many radio frequencies used twice by so-called secondary users. The secondary user can use the spectrum as long as the first user do not use it. This is e.g. in the 5G with Wifi.
This legislation is to (hopefully) assure that everybody plays by the rules. This realized by certifications. But the problematic nature of SDR is, that software controls the behavior and software can be replaced easily. For that reason none of those people, which govern the radio usage, like SDR. They want to lock down the device, so that they are sure that every body plays by the rules.
- wyager 11y agoAs you said, this law is immediately rendered pointless by the existence of SDR. It doesn't matter what the regulators' pie-in-the-sky intentions are; they are actively making life more inconvenient while accomplishing nothing. Anyone who can replace a baseband firmware can also build or acquire hardware that is capable of WiFi-range TX.

You are allowed to hack your veichle, but if you fail to keep the highway code or exceed the allowed limits, you will get some. But you are free and not treated like a criminal up until then.
