Going further the students who were pressurized to take up engineering are now using these jobs as stepping stones to reach a point where they can pursue their real interest. The good engineers are seen as capable to lead bigger teams and pressurized to enter project management (which is, in reality, resource management).
At least on the open source front, there seems to be a real community of interest in India, who seem to involved due to their love in the area. The way I see it, getting into engineering was an 'arbitrage opportunity'. That window has closed and people will slowly move on.
