Okay I don't get it.
No. You don't. It must suck to be you, stumbling through life so clueless and stupid.
There were links. They provide copious information, lots of vocabulary to search out the issues. If you can't read for comprehension and do your own homework, don't think for a minute I'm going to waste my time trying to "explain" anything to you. It's pretty clear where you're coming from and I won't engage you in your "I haz a unconcerned and MICROSOFT IZ T3H AWSOMES" trolling.
They clearly state - information about apps might (=absolutely will) get sent
if you do not TURN it OFF. And then here comes pro Linux and pro Apple fans - "OOOH THAT
SLEAZY MS SNEAKING SPYWARE... OH NOOO, NOT JUST IN WIN8, BUT VIA SNEAKY SSSSNEAKY (MASKED AS A IMPORTANT SECURITY, SO SNEAKY ZOMG) WIN7 PATCH (
maybe)".

If you sign up for "I want to get fucked" and then you get fucked, deal with it and maybe you're the clueless one.
Still don't get what's all the fuzz about. If they were to send information and I couldn't prevent - yea, I would go back to FreeBSD or ArchLinux.
The bigger concern though, as that Ars article pointed out, is that every single Metro app HAS to be installed via the Windows store. So, in other words, every program that makes any use of the new Windows 8 features, has to be downloaded straight from Microsoft anyway. Who can then link that data to, at the least an email address, and potentially a name and billing information too.
Okay, deleting (or will those sleazy bastards will really delete my profile??) Facebook, Gmail, Steam, Origin, Battle.net, Paypal, eBay, Amazon (omg they know what I buy :OOOOOO), Last.fm, xBox Live, PSN accounts. And my bank's e-system account. Because... Damn, they know my incomes, what and how much I pay for and OMG OMG OMG OOOOOMMMMMGG. And then smash my phone - they know what numbers I called.
Oh wait, welcome to 21st century, it must be new to you.
