Yeah, I dont think is that critical. The average Joe can't really use the full bandwidth of WiFi 6 and I don't think we already live in the world of everything is WiFi 6, a lot of device still use the 2.4 and 5 frequency.
A only European plane is not for tomorrow. There are plenty of part that European don't manufacture in the A320 like electronic and engine.
And the engine in the stories is half American Half french.
Boycotting aircraft will be a harder process. Airbus is in a strong position as Boeing struggle with QA and production rate. Every body is looking to buy a A320. They buy a Boeing because Airbus have such a waiting list that your plane won't be delivered before 2030.
So maybe let just ask Airbus or the Europeans Commission to invest and plan for a 100% European part plane.
Same, but I don't have room/money for it so I just watch motorsports.
