Why do we have to jailbreak thins using opensource software? EU right to repair, should be extended to right to patch, hack, tinker.
That might have changed now, but I still can't find an official repo. You could look for older versions like this: https://github.com/robimarko/routeros-GPL or try to contact them directly (or sue if you think you have a standing).
The EU imposed software radio lockdown, there was a public consultation about it where most of the answers from industry and users were negative, but they kept on pushing for it.
The same kind of consultation happened in the US, with the same kind of ignorance.
We could have cooperative use of the airwaves and true open-source, open-hardware radios, but there's too much money to be made auctioning spectrum and assuring that most of it is is 99.99% unutilized. Would be horrible if people had cheap 5-10W handhelds that use advanced codecs, or could run 5mw of power on any part of the spectrum.
