This notion that surefire mark enforcement can only be achieved through blanket legal action against all potential abusers of the mark is parroted on HN repeatedly; however, the real world situation is a bit more complex. A firm will not lose their trademarks if they don't aggressively sue each and every person/business who might potentially be infringing upon the firm's marks. In fact, for firms like Red Hat who are actively selling a product, (and therefore utilizing the mark in commerce and in a way that makes that mark very well known to potential customers) said ongoing business operations typically ensure that courts will regard one's mark as defended and active, especially if one ensures that the firm does go after the most very egregious violations. TL;DR: Firms do not need to obsessively litigate against every single person using their mark.
