I generally agree with you, but the counter argument would be something like, If you opened a soup kitchen downtown to provide food for the homeless, should you be required to install accessibility facilities (ramps, elevator, bathroom, etc.)?
I know the law says yes, but is it what we want? Have the extra building codes discouraged potential altruists?
I wonder if there's a government subsidy for that part of it, and if so could a similar provision be allowed for educational institutions opening their courseware.
