It can be seen that the providers of access to computing have roughly divided the things computer can do into two categories, certain things computers can do to which every computer user ought to have access, or maybe must have access, or maybe at least to which every user will have access, and things computers can do to which users can have access only, let us say, under limited circumstances.
The criteria for assigning one or another function to one or the other of these categories could be discussed at length, or perhaps without end, which suggests that, if our purpose is to get something done, that might not be the ideal course of action. I want better access to CAD, which seems to have been assigned to the second category, which I think is somewhat outrageous, but what can I do about it? The providers of CAD probably won't be much impressed by my outrage - they are unlikely even to ever be aware of it - I might prefer they not be. This leaves me to ask what I can do, besides protesting the existing state of affairs, to move CAD into the first category, that is, to make it a function every computer user has access to by default.
