Googlers should be required to develop their apps on 5 year old computers with a network connection capped at 1mbps with 100ms latency. On this flight today I've tried to use Gmail, Google Flights, and Adsense, and they are either ridiculously slow or just don't work.

I hear you, but I wonder if you don't have it backwards. 2020 is the year and airlines WiFi is like 1995 dialup? Something is wrong and I think it may be in the sky.

I don't think that's fair to say until you've personally had to maintain a wifi network that supports 300 simultaneous connections where the only uplink is an unstable satellite or cellular connection.

They may be simultaneous connections but you make it sound like a server farm. They are "periodic" demands for upload or download. Maybe 30% of 300 seats are connected, for 90 connections. 10% hit the return key at the same moment, for 9 hits to the uplink at any instance.
