No, not really. I have code written for the Comodo API from before I spoke to Digicert. I would get a MUCH larger cut for that than I do Digicert.

Yes. The Symantec reseller agreement (remember, GeoTrust is a brand not a company) explicitly forbids you from contradicting their marketing.
Also: part of doing good in the world in not supporting people who trick others.
