We are having a lot of fun at StackExchange sites and creating a huge base of knowledge. However, one sad day we may wake up and see that:
- SE can be only accessed by predefined set of people (for example: "only for SE employees", "only for the US army", "only for users with at least 1000 reputation", "only for active and successful users")
- SE demands payment for accessing Q&A base
- I can only read those parts of the SE Q&A base which I helped to create (posted, edited, voted, etc).
- SE allows its knowledge only to be used for certain goals (ex: "you may not consult StackOverflow create a computer program which will be sold to someone", "you cannot learn for your university exam from SE", "you cannot use RPG SE to help you with your job as a professional game master", "you cannot print and sell a book with SE posts", "you cannot ask Law SE for how long you should put that guy into prison") [yes, I know it's hard to prove]
- SE "buys" the knowledgebase for bazillion of dollars from the people all around the world and then does some of 1), 2), 3), 4).
Of course, StackExchange (the company) can be shut down and their servers turned off/fail. This is not the problem which I am asking about.
So, can StackExchange restrict access to its content (for example by doing one of the above options)?
Note: I am afraid that asking about each of those 5 points would qualify my question for closing as "too broad", therefore please focus on the question in title.
