The eventual winners...
...cannot be the end users because the markets are rigged to reward stake holders first. Blocking this merger outright is the best chance the governments can give the end user. This is a classic case of a corporation that cannot tell the difference between `Too Much' and `Not Enough' and I believe that any expansions on the part of Microsoft without full public disclosure will do them a great harm in the long run. They need to be honest and open like the FLOSS ecosystem if they do not want another user revolt (github) to happen.
Anyone have a better point of view?
