I guess your voice will never be heard by the government, then--because there's no means for you to say anything to them without their asking you who you are, where you are, and other various details about you.
Your opinion is meaningless to them if they don't know who you are.
As for their collecting information about my operating system--if you visit my website, I do that too. It's part of my stat counter. Do I actually care? No, not really, but the info is there. If people have problems with the site, and I notice they're all people using the same operating system, I have a better chance of fixing my site to work with them.
People spend too much time worrying about who's collecting information about them, without actually stopping to ask themselves whether they actually care if anyone has that information.
