This is such a good point. I've been pushing back for quite a while, and have generally had a positive response where the company revises the contract wording to a more acceptable level.
I feel that the principle of least privilege would be a good point for employment contracts to start, rather than the current approach of "try get control over everything employee might think of whilst employed, even if it's during their own time and unrelated to the business"
