If I wasn't certain Apple will do their best to patch every avenue to this working in the future it might be motivation to buy AirPods.
I would be surprised if they could. Linux on Macs is still a thing. In fact, Linux on Mac is why I keep all the Macs we have in the house from the mid to late 2000s because they still turn on and work, if I choose to install Linux on any of them they are still usable.
The AirPods already work outside of the Apple ecosystem. This is just someone building out interfaces for their extra features that are already integrated into Apple operating systems.
