Here's how I think about it. All companies have one goal: to make money. Good ones do everything within the law to make as much money as possible. One way to do that is to have greater marketshare than the competition. One way to do THAT is to have a product that stands out on the shelves. Marker's, more than any of its competitors, has done that. That has made them money. So they are going to do everything in their means to protect that advantage.
Whether I find that distasteful or not, that's what a company does. A company that doesn't try to make as much money as possible is not a company at all. It's a charity or a social club. As the old saying goes, you can't beat a dog for chasin' his tail.
