Video conferencing isn't the only use for upload bandwidth. There are lots of other use-cases which are much more mainstream, like streaming, YouTube uploads, backups (lots of phones these days do photo/video backups automatically), photo sharing, etc. Downloads are still more common of course, but these days I'd say upload bandwidth gets used far more than it ever has in the past.

Every use case you’ve given are minority use cases or power users. I’d say less than 5% of subscribers do the above and most do not use a lot of upstream bandwidth. Most phones do the backups at night when most people are sleeping.

> There is a reason why uploads are so limited for consumers.

and that reason is that DOCSIS allocates more channels for down than up. and DOCSIS does that because that's what most consumers want.

Over copper it's easier to provide asymetric connections because the provider can better manage interference between different cables. When there's no interference problem it's only a question of allocating the bandwidth. Ideally the connection would auto-adjust and provide up to the full bandwidth in both directions instead of constant half/half or 0.9/0.1.

Comcast Business operates on a 10:1 dL/uL ratio, at least here in Colorado. We have 300/30mbps, no option of 200/100 etc.

Could you get a dedicated fiber connection for your business? Those things cost a bit more.
