* malware-like behaviour through "legitimate" software update channels, force-feeding windows 10 on unwilling customers

* their abysmal, hard-to-use new directions in UI design (flat, 2D, no contrast, paper-like, or even metro for that matter)
I can already think of three to four nasty ways they can leverage (abuse) all the LinkedIn user information, work history, contacts, and networks, and I'm sure they will do it based on their recent user-antagonistic behaviour.
Oh, but they've nicely polished up their PR machinery so everything's cool now.
