There are indeed a lot of things in Windows 10 that can, and I do say CAN, enable Microsoft to find out a lot of things about you, the way you use your PC and the things you are interested in. These things have a certain commercial value.
BUT, there's always a but, people who're PC savvy and who will take their time to find out about the new OS, will be able to turn these things off.
You simply need to go to settings and then privacy. You can even disable them in the registry.
But finally, the sources mentioned:
Aren't the most trustworthy of all. Russia Today? Conservative Focus? Hell, you could even call Fox News "fair and balanced"... None of those sources (Fox included) are trustworthy and all have a hidden agenda.
I'm the first person in the world that will say that Microsoft doesn't always have our interests at heart. But there are worse people and firms around. Politicians and banks to name just two.
The main thing is that Windows 10 is the future. And the future looks very promising indeed!
