While I didn't know anything about those useless service, I don't think Vistaprint becomes a $1.9B company just because they do shady things. As an entrepreneur, I would love to learn about how others build their companies but it doesn't mean we have to agree all of their moves.

I don't want to argue about the ethical issues here. But I believe every company has done something in the gray area. Do you think all those Google ads on domain parking pages are click scam? I do.
