OpenBSD has supported 11ac for several years, and has the iwx(4) driver for modern Intel WiFi cards. There's also support for Broadcom FullMAC, bwfm(4), which is on e.g: Apple Silicon machines.
HaikuOS also has a port of OpenBSD's iwm/iwx drivers.
FreeBSD just recently announced they've started porting the OpenBSD iwx driver.. from Haiku.
Not OP, but they've raised $4,974,668 since 2014 (done by adding up all the thermometers at https://github.com/bob-beck/foundation-web), and I'm excluding anything prior.
