yes and we will need sandpaper also to remove all brand names from the various parts of the laptops - and inspectors to make sure none of the laptops have any patented or proprietary hardware. Also non-GNU/Linux cellphones will be confiscated and destroyed.
Just wondering what's wrong in expecting that speaker should not use non-GNU laptop in giving he presentation.We are not those guys who are working for Microsoft's competent whose only motive is to kill open source.
Do you like to step on *two boats ( Proprietary + FOSS ) at a time* ?
You can allow others to use any OS (it depends on their choice /* A lot of open source developer especially those working with python use M$ as their primary OS* , their is nothing wrong with that ) , but atleast they should use GNU laptop for giving the presentation/talks/workshops.
