I wouldn't take a willingness of many people to accuse someone of a crime as evidence of it. It's also counterproductive, furthering the believe that "all politicians are corrupt" without evidence. If that's the reaction you get for any decision that is mildly controversial, you may actually start considering it.

There's also Occam's razor: less than 2% of people choose Linux on the desktop. Maybe it's just not that good for this purpose.

Linux advocacy has also changed. It's now so entrenched on the server that the quest to get it on desktops is less relevant. A lot of the OSS advocacy was also aimed at proprietary formats, and the web (mostly google docs) has increased competition for MS Office more than OpenOffice ever dreamt of.
