It's not about a crummy e-mail address, it's about privacy, trust and freedom, things which you get by default with libre software tools and things which Microsoft has not proven that they can deliver.
And that software is not really free, it comes with a nice lock-in in the form of .NET and C#, two technologies under Microsoft's control.
After MS has a track record of at least ten years of doing this open source stuff they will get a break.
This thread is proof that for many getting stuff for free is enough to forget a long corporate history and throw their caution to the wind.
On the other side, I wish app stores required submitting all source code and not binaries. Then, the store would build the app binaries on their end and keep the source code archive somewhere.
Also give the developer an option to make the source code publicly available. How great would that be!
