Anyways, as to your "root kit" theory, anyone with basic computer knowledge would find this -

And if you're really worried, you can go here:

That's not a long page to comprehend. Anyone with basic literacy skills would draw three key pieces of information from that link:
1) Like any good malware, it reinstalls itself if you don't eradicate every last piece of the infection.
2) Every last piece of the infection includes "any Google programs".
3) There is no uninstall, instead you must go into Terminal, hunt down the offending process which could be in a couple of places, and rm it as superuser.
This has all the hallmarks of a Bad Thing: This software is installed stealthily. It has root privilege to circumvent proper permissions control. It has no UI to indicate that it's there at all, that it's modifying your system, or to control its behavior. It has no uninstalller and requires more advanced skills to remove it than to install it. If incompletely removed, it reinstalls itself without notice. It has built up a cottage industry of vaccination tools.
Sorry, I know you want to believe that Uncle Google has your best interests in mind, but this doesn't sound like the behavior or removal instructions for something happy.
Next time you might benefit from reading your own posts to determine if you're supporting your own point or the one you're arguing against. If they're supporting the point you're arguing against then stop arguing, concede the point, and offer the information neutrally.
It's clear I hurt your feelings.
...
But I know, Google is out to get you and destroy your life.

Hurt my feelings because someone on the internet doesn't understand the technology they use? Hardly. It's sad, but in the same way homelessness is sad. I'd like to help, but sometimes people need to want to be helped.
Irritated me because I'm tired of seeing a forum I've been coming to for a decade, and where I used to be able to have intelligent conversations, get overrun by hair triggered zealots ready to surround and bludgeon anyone they suspect of a thought crime against Google? Yeah, that's closer to the mark.
You'll notice I didn't say anywhere that Google was out to get anyone. I didn't say anywhere that Google Software Update was after my personal information. I never drew a comparison between Google and any other company. I simply expressed dismay that the software I paid for contained a component that I and others see as badly designed and dangerous, and that this software was inseparable from my purchase without freezing my new purchase in time. I shared my experience so others would be aware of this fact.
You, on the other hand, seem to feel I've offended your one true god and you must enter the belly of the beast and slay those you suspect of worshipping false idols.
