Common sense lacking within a demanding populace.
Take a business that sells physical goods and offers a showroom to allow the public to browse and make purchases. Do you give the general public access to the warehouse behind the showroom?
Take the warehouse behind the showroom, this place deals with order fulfillment. Couriers are given special access to controlled areas of the warehouse so that the couriers can provide their intended service to the business. Do you give the couriers access to the administrative offices above the showroom and warehouse?
Environments need to be controlled by the business that creates them, otherwise things go wrong. Poor practices by third parties in an unregulated environment can lead to disastrous consequences.
Okay how about another analogy? You rent an appartment in a block of flats. Part of your agreement with the landlord will prohibit you from accessing certain areas of the block of flats, examples such as closets storing maintenance equipment or roof cavities (lofts or attics) come to mind. You are denied access to those areas for your own good and the good of others within that block of flats, regardless of what your personal opinion on the matter may be.
Some of you may feel that you have every right to explore every last bit of functionality included within the server operating systems you use. If you are one of these people, then please start making demands on all other commodities that regulate access to certain features or areas. You won't get very far, but it would be interesting to see the same peculiar logic derived from law applied to the software world becoming apparent in more common aspects of our daily lives. It is somewhat amusing to consider the consequences, and in the midst of that mirth the realisation of the implications to the software world are revealed.
