Because a household family uses internet for more then a single zoom video. If I have two kids and work from home, 3Mbps isn’t sufficient to support a house.

Or if you have two people at home working and doing web meetings. I've learned that lesson during COVID.

That problem can be solved very easily and very cheaply with better communication and scheduling rather than any sort of tech though.

Have all companies schedule all of their meetings based on their employee's housemates' meeting schedules in a different company? That doesn't sound very easy.

That's like saying we should just work different hours. Boom simple solution, just need to get 20 other people on board to work nights instead of days.
