Just to show you how thorough some of these programs are I took I survey from steam a while back. It cataloged every and I do mean EVERY program that was on my computer. As to what they do with that information its hard to say but by consenting to that agreement if they find something they don't like they could do something to me. Luckily all my stuff is legitimately owned so I have nothing to fear though letting companies rummage around in my closet for skeletons is a bit rude.
BTW: You can find all that data back on the Steam site and see how popular it was among the Steam users. Gamers used that data sometime ago: TW2 was about to support monitors with an aspect ratio of 16:9 only. With a bit of work we could calculate that this only represents about 30% of the gamers on Steam. Monitors with 16:10 were good for 40% and the rest for the remaining 30%. That allowed us to pressure CDPR to release a patch as soon as possible.
At least Steam's data is public. It is handy for developers to know in case they want to support specific hardware or software. That doesn't mean I like software snooping around like that, but it is better than EA collecting unknown data and dumping it into the company's commercial void.
