Also, Mono's own ecosystem of additional libraries works better on Windows than on Linux. A while ago, I used a project that used an SQLite binding from the Mono project. They decided to discontinue development of this library in favour of a newer alternative, and it was then totally broken by subsequent Mono updates - but it continued to work fine on Windows with .Net. So any projects that still use this library are basically impossible to get working on Linux/Mac because Mono has awful backwards compatibility with the Mono Project's own libraries compared with .Net.
Quite funny that you try to generalize a statement from what appears to be just one single example (note: mono developer here and this is the first news I have about a fuckup like this).
It comes with the territory, I'm afraid. Some users will try something once, find a bug or limitation, decide the platform sucks and never touch it again (and if the platform is worthless, why bother filing a bug report.) I've been guilty of it myself quite a few times. First impressions count for a lot, and they can be difficult to control.
