WiFi 6 works fine on OpenWRT, you can check if your specific hardware would be supported here: https://openwrt.org/toh/views/toh_available_16128_ax-wifi
EDIT: although, for OpenWRT I’d recommend a router with openwrt with a separate WiFi AP (Zyxel makes good ones) as opposed to bundling them all in one.
When it comes to music streaming, it’s a little simplistic to state only their COO, also important to note how much each service pays out to the artists (many of whom are European). Tidal is originally Norwegian but due to financial difficulties now has majority ownership by Block Inc. its true, but it also has one of the highest per stream payouts to artists.
Qobuz does too, and that’s a French company.
Ofc music streaming in general is never going to compensate artists as much as buying a CD/Vinyl/Tape or going to a concert.
