A proposal to require certification of all IT practitioners is shocking to some but Malaysia is considering it. I imagine there would be a transitional period. The government of Malaysia widely uses and promotes GNU/Linux so I would bet re-education of many IT practitioners would be required.
The problem with such proposals is that it is a barrier to entry for youth/poor so there could be some constriction of labour in the field. On the other hand, education can take care of that.
In any event, I see this as an opportunity for GNU/Linux to grow as self-education in GNU/Linux is fairly straight-forward due to the openness of FLOSS. Students can legally examine the code and install/configure GNU/Linux as often as they want without requiring a licence. That other OS restricts everything to payments.
