Yes, all your keystrokes are sent to NSA/GCHQ and other government agencies around the globe, what do you think?
I have to say that this topic about privacy is going beyond belief and people who bash at w10 use this as an argument because all other arguments in terms of performance, security enhancement etc are invalid as a reason as to why W7 or 8.1 for that matter is better than 10.
if we strictly compare to hardware wise, some hardware still has hiccups (but then again its the vendors that need to keep up with the OS changes and compatibility)
Quality of life features such as updates (how they are handled) etc, sorry either you deal with it or find ways around it. You can't please everyone. Plus is a known fact that you give 20 users the option to manually check for updates, guarantee you 5 of them wont, simply because they are just that average user who uses the system for web surfing or facebooking or even casual games.
Notice where exactly are the people bashing W10? Yep securiy/os forums. You hardly see bashing in IT fields (specialized in programming language/networking etc). Then notice exactly the arguments why they think W7 is better than W10, excluding the old excuse of privacy, because lets be honest, if you think for a second that not one single service you use is not tracked one way or another, then you have a lot to learn.
In regards to W10 usage by the user, I will ask this, how many of you actually bothered reading the User Agreement when you installed Windows 10? If you do not agree with how W10 as an OS operate, then by all means use another OS, but lets not forget that until June or so, any W10 user who comes from W7/8.1 is given the free upgrade to W10.
Fun Fact: Linux community has its problems but the W10 hate club community is far more amusing. At least in the Linux community we have actual facts to backup most opinions.
