This is a blatant abuse and they should be sued and shut down. This is beyond unacceptable. There is no reason to do this kind of thing.
The obvious reason for doing this kind of thing is their target market & 99.9% of sales are to people using them with phones, so Jabra has no business reason to spend money providing customer support for PC interoperability.
It actually is. If you use either the Bluetooth patents or trademarks (e.g. logos and names), not only you must pass a certification that ensures this, you must also "maintain a level of quality that meets or exceeds industry standards", and this evidently doesn't.
I definitely use my macbook with non-apple hardware. From headphones to laptops to android phones.
My first Macbook used to pair with a Nokia E72 to get internet via the GSM modem, I used it every day on the train.
Two weeks ago I connected an old Oneplus One via bluetooth to my macbook (2020 mbp) to get some old photos from its internal memory.
What doesn't work?
EDIT: actually, I'm not sure I ever connected a laptop to a macbook, but I have a linux laptop so I can try it if you want.
I’ve never had any non-Apple phones/computers not work with Apple phones/computers using Bluetooth.
