Very insightful and well articulated.
But why are you posting this as an AC in the comments to some other article? If you were to clean this rant up a bit and write it up a bit more thoroughly, you could submit it to any of a dozen techie and/or FOSS oriented websites/blogs and probably get it published. You might even get paid for it, but that's beside the point. Even if you didn't find a blog willing to print your article, you could put it on your own site. Next, submit a link to it as a story here on Slashdot, which would get your ideas a lot more attention than your AC comment is likely to (I just checked and the poll you linked is still at 15 votes). It is entirely possible to get Slashdotters to make a difference, but it takes a bit more work than just ranting in the comments of random articles.
Don't just complain about lack of mobilization, make it happen!
