If I misunderstand you please correct me.
If that is what you contend, then you have no addressed whether or not the market allows them to do otherwise. You take for granted that the market is free and that people are willingly choosing this outcome with perfect knowledge and without any incentives or forces which would compel them to act despite not wanting to be screwed. For instance, if you do not have bargaining power with a company over your contract, you have no choice but to accept it. Can you enter into negotiations before agreeing to a EULA?
There are forces that are not free market forces which constrain actions, there is human tendency to prioritize immediate needs over long term benefits, etc which all play a role.
The fact that:
1. The market exists 2. We have a conception of how the market should work in an ideal 3. People act in a certain way
do not all combine to make it true that 'people prefer it this way'.
That's the point I am making in counter to your assertion.
