The trick in my area is my ISP is a crown corporation that competes with the privately owned ISPs. They don’t give a crap what you do(as long as it’s not too illegal or damaging their service), the standard on their fiber is upload speeds are 1/2 the download speed and you can pay an extra $10/month for symmetrical. I put it to the test once as I was testing online backuo software. GDrive has a limit of 750 GB/day uploaded data, and I did that consistently for a couple months straight(IIRC that was pretty close to maxing my upstream at that time). Never heard a peep.
