You and the parent are both right. The problem with Comcast is that many people (I being one of them) have no choice in the matter. It doesn't matter how much I despise my ISP, for they are literally the only game in town. My vocation dictates I have high-speed internet, thus I'm forced to work with Comcast.
Shaming Lenovo or its partners can make a difference because people do have a choice here. There are many laptop vendors out there. And if "Vintage Investment Partners" becomes well enough known as something the public finds distasteful, it could conceivably cause other companies to shun them as well.
You know, at least until they change their name. Still, I'd argue that if people cared enough, this approach would work in non-monopolistic cases.
