The introduction of Mono into Linux and the open source environment begs risking patent claims from Microsoft. Free Software Foundation founder Richard Stallman sees it that way. The Technical board at Ubuntu, on the other hand, doesn't consider it any reason to be disturbed.

Now that Microsoft formally recognises the contribution of Miguel de Icaza to Microsoft, there is no longer any reason to think of Mono as beneficial to GNU/Linux

Those who dislike Mono to the extent that, they would like to avoid mono based software as best as they can, are getting larger everyday. But when you install a software you never know if it contains Mono or not. That is where Mononono(sounds real funny, eh?) comes in. Mononono creates an intentional conflict with mono packages and thus making it easy.

In short, we are in an adversarial situation. Microsoft does not want us to succeed. Thus we cannot trust Microsoft, even if we'd like to, and must consider Mono based upon the question "What is the worst thing MS can reasonably do?". We can only trust Mono if we are convinced Microsoft doesn't have weasel room. The current situation appears, to me, to have lots of weasel room.

The Mono riddle begs for source of the claims of "demand"

Microsoft has shown the world exactly how friendly it is towards open source by going to court to claim damages over patents which have been allegedly violated in an implementation of the Linux kernel. And that's a good reason why FOSS users should avoid Mono and Moonlight like the plague.

More than a month after the BSI, a German IT security federal agency, issued a warning about a high-risk vulnerability in Windows7, Microsoft has finally decided to warn their customers in a security advisory.

There has been a lot of pro-Mono and anti-Mono arguments assaulting the community of late. The debate is not new but both sides have taken up arms since some distributions have decided to either remove Mono or include Mono by default.

Windows is promoted at the expense of Free software and Linux because Novell's Mono endeavours are increased and get a new name: "MonoDroid"
