That's a pretty strong opinion on something so widely deployed and can work without any problems in a place which is very polluted with radio traffic and jamming in some frequencies.
I had a Microsoft Bluetooth mouse which constantly lost connection where I live. No Logitech receiver even skipped in that place.
You say it is an opinion but Logitech did abandon the receiver because they could not fix the security and instead released the Logitech Bolt with encrypted communication between peripherals, in order to not lose more corporate customers due to crappy security.
If my mind is not playing games with me, Unifying is around 10 years old at this point. It might be inadequate in today’s world, but it had a pretty good run for something like that.
They may had to make breaking changes to it at some point, but it’s already old technology, so moving to bolt doesn’t make Logitech an incompetent company in my eyes.
