Documentation: Upload-Helper: Wording: Neutral term instead of "consumer"

[hacklschorsch]

Greg Troxel suggested an improvement for the Tahoe-LAFS upload helper documentation (copy-pasted from the ​Tahoe-LAFS Mobile issue tracker ):

I suggest editing out the word "consumer". That's a political word that labels individuals as existing to buy things from companies, rather than a neutral term. It's also wrong; lots of businesses use cable modems that are asymmetric too. I would suggest just "DSL", but given that DSL is fading, and the concept is really "asymmetric", say that instead, as in

Unfortunately, this “expansion penalty” occurs in the upstream direction, and many Internet access connections (DSL, cable modems, cellular) have much lower upstream capacity then downstream capacity.)
