Casual people and scientist are different cohorts of population, casual people do not have the culture to comprehend, most do not even understand the difference between a third-partly hosted web-app and a local one just because they look at the same screen, most do not understand why it's absurd and bad print a document, scan in to an image and send the image by mail etc BUT those normally are not scientist.
Scientist normally like to learn, so if someone explain them something interesting they learn it in means.
Population always follow.
Just look at the French Revolutions the Sans-culottes was driven by bourgeois, similarly on the other sides soldiers are peoples/"commoners" driven by other bourgeois and aristocrats. The people have chosen a side or another, and they are pushed to chose by both sides. So far I do not see much on the FLOSS side since there is no community anymore and most just live on someone else computer. Who better than Scientist can correct that aim? Peoples in Humanities surely are more listening but they mostly lack enough skill to bridge the gap between the philosophy (in the classical sense of "the why") and the practice, scientist normally can.
