Well, I vowed never to give a cent to Microsoft again, so there goes any Minecraft upgrade I've considered. Not that they will be aching, but nonetheless...

Skype seems to have gone from a rising trend to a falling one (now at 65% of the 2011 "interest") following the MS acquisition. Yes, that's partially with WebRTC, Hangouts and other outside influences but MS's actions (further centralising control) put many people off who wouldn't be simply put off by the name.
How much of a role do you really think that plays in Skype? Honestly, Skype is so widespread that I'd bet the average Skype user (a) doesn't realize it's owned by Microsoft and (b) hasn't really cared about the changes Microsoft made post-acquisition. I could be wrong, but from my perspective it seems that the average Skype user really doesn't think about these things.
Talking about Skype... I was a long time MSN user and ditched it and they forced every MSN user to migrate to Skype. No, I don't miss it at all. What I've done was taking my friends with me to use XMPP.
