> I'm from a third world country, so I won't be able to alter contract clauses
Just because you need a job doesn't mean you should accept whatever the company offers. You should be assertive and inquisitive when it comes to these kinds of clauses, especially at new jobs. I've had contracts altered slightly or completely before starting with a company, from things like where and with whom I get to work after I leave, to IP. Even if company says that this is a deal breaker for them and that the clause has to stay, and you choose to accept, I think it's good to at least demonstrate that your objection.
