I think using a domain name you paid dearly for, to promote a project you've got millions invested in, and many ancillary businesses in the space you also have millions invested in is entirely ethical. Do you think searchengine.com is unethical because google exists? I'm pretty sure Ver is a bitcoin maximalist as well.

Yeah, I don't think you've supported the "dubious" claim. Also his attempt to create lower fees through software "upgrades" may be flawed, but the intent seems honest to me.
