Logitech's POP switches will become electronic waste by 15 October https://www.heise.de/en/news/EOL-Logitech-s-POP-switches-will-become-electronic-waste-in-a-fortnight-10702287.html (thanks @ber for the pointer).

Does anyone of you know if you can still use them with #FreeSoftware or if they are really complete waste afterwards and the only lesson people can learn out of that is, that they should not buy such devices which depend on proprietary software?
