> contracts the courts won't enforce, even though they are otherwise legal and valid, because it is unfair.
is there some kind of common law that would indicate what sort of contract would be deemed unfair? Because a lot of contracts seems to be drafted in favour of one party, and the expense of the other, simply because of power imbalance. Employment non-compete contracts tend to have this property. What about assymptotic licensing like those of software/service EULA (e.g., where they have a clause that says they can terminate your service for whatever reason they desire).

The controlling law for a specific contract would come from stare decisis or the precedent as set by case law.
Your gut it on point, because although employers get away with a lot, it is one of the areas courts are likely to find contracts to be unconscionable as a natural result of the unlevel playing field between the two parties.

Definitely, and it leads to very specific case law. For example, case law might be specific to a profession (say a doctor) and geography (any restriction on competition outside of 20 miles is unenforceable). Keep in mind case law is jurisdiction specific, so say a 20 mile radius non-compete against a doctor in a major city might be enforceable, but in another jurisdiction say a small town where there are only two licensed doctors, the court may very well find it would be unconscionable to enforce the non-compete because it would limit the communities access to healthcare.

It is difficult to try to answer legal questions in a vacuum without a specific set of facts, but as a general rule you can certainly have a contractual right to terminate the contract. Another general rule would be the courts are more likely to provide damages than any equitable relief, meaning, say my EULA didn't include the a termination provision, then I stop providing you access to my software and you sue me. If the court agrees with you, the court's ruling is far more likely to have me pay you the monetary damages you suffered before they are to order me to continue providing you the software under the contract (though there is always exceptions and some cases the court will make a party actually perform the contract).
