"Running counter to this success is a steady stream of criticism that is so strong that, in many free software circles, it is better known than Mono's success. "The hostility started on day one, you know?" de Icaza says. "A lot of people are not pro-something; they're anti-Microsoft. And Mono was criticized early on because Microsoft created the APIs, and Microsoft is evil."
"De Icaza suggests that a certain double standard has been present in much of the criticism. He notes, for example, that the same people who criticized Mono, which has always been free software and cross-platform, used to be far more tolerant towards Sun Microsystems'Java when it was still proprietary and ran only on platforms that Sun chose to support."
