Yeah, keeping damn thing for ONE dumb and crappy application. This is just ridiculous. If you use tomboy, because it's more stable (I really doubt, because Gnote seems to be very stable and it's slimmer and faster same time) and has more features then why don't you switch to KDE where there are more features then in Gnome? Oracle is suing them, because they violated some term. Stop spreading FUD. Probably nobody's getting sued over CLR or Mono, because nearly nobody uses this crap.
3. I defend Mono because there are some really good apps made with it (personally I absolutely love Banshee, Tomboy is a lot more stable and has more features than Gnote, Monodevelop is a pretty decent IDE, etc) Insisting that they should be removed from distros and ostracised today because of the entirely hypothetical possibility that at some unspecified point in the future, Microsoft might try to enforce patents on some technology that they don't even depend on, is ridiculous. Incidentally, all the various JVM implementations and Java frameworks and libraries don't seem to worry anyone, and yet, while AFAIK nobody is getting sued over CLR or Mono, Oracle is suing Google over Java right now.
Get the hell out with such ms bullshit out of here. Better check how many patents ms breaks. And Linux is here to compete with ms not to serve them.
4. I presume that the anti-Mono crowd will never ever ever install the Linux kernel either. The kernel supposedly violates over 120 Microsoft patents (which is probably a lot more than the number of ASP.NET patents) and Microsoft has explicitly said they might consider enforcing those, contrary to the Mono ones.
