I'm not sure if that's safe either. I installed Windows 10 recently and the install included apps like Facebook and Twitter. In fact a good portion of the start menu was essentially mini-billboards.

this reminds me of the android marketplace, where, in order to get a nice, clean, stock android installation (as opposed to an "enhanced" OEM android flavor), some consumers are eager to buy a device directly from Google.

interesting that a significant (supposed) advantage of separating the software company (e.g. MS, or Google) from the hardware company (e.g. Lenovo, Samsung) -- of making the software generic and capable of running on a broad universe of devices -- also became a powerful source of FUD.
