Miguel de Icaza

Miguel de Icaza is an ardent and longtime Microsoft proponent who worked in Xamarin on projects such as Mono. Eventually Microsoft rewarded him with a high-profile job, as almost everybody had expected.

We wrote about him in many articles such as the following (starting with most recent).

Update (2016): Miguel de Icaza has, unsurprisingly, joined Microsoft and received a lot of money (millions) from the company in the process.

Update (2021): Nat Friedman and Miguel de Icaza are no longer friend. Nat Friedman has in fact been eliminated.
