I've been using wifi on Linux since the ndiswrapper days. I haven't had a wifi issue in many many years using Lenovo, Dell, Panasonic laptops and various self built servers (but they tend to be wired)
This is an admission that HW4 will not be sufficient. If you bought FSD, they will have to upgrade your hardware whenifer they declare it "autonomous".
It also limits the refunds they may have to issue in California.
Back on the old days, we used windows wifi drivers on Linux via ndiswrappers.
