Just because someone isn't targeting you doesn't mean they aren't innovating.
It reeks of HN bias that no one in their right mind should ever become an employee of some corporation because they aren't making a shiny box or a X, Y, Z website (substitute your favorite tech of the month for X, Y, and Z)
If you're not innovating in an area, you aren't furthering "the Progress of Science and useful Arts". Unfortunately, 35 U.S.C. § 271(d)(4) makes it ok to do nothing with a patent except sue, so you aren't doing anything illegal, but you sure as hell are gaming the system.
