Intel isn't going anywhere for at least a couple of hardware genrations. Buying a GPU is also not "investing" in anything. In 2 years' time you can replace it whith whatever is best value for money at that time.

I agree entirely.
My point was that even if Intel disappeared tomorrow, there's a good chance that Linux developer community would take over maintenance of those drivers.
In contrast to, e.g., 10-years-ago nvidia, where IIUC it was very difficult for outsiders to obtain the documentation needed to write proper drivers for their GPUs.
