There are literally thousands of reasons to live anywhere, and it turns out that Massachusetts measures real well on a lot of them. If you base your living decisions on "there might in the nebulous future be an onerous non-compete I can't get an employer, who is trying to be appealing to me and in an industry as stupid-hot as tech is almost never the only game in town, to redline", I envy your few and trivial problems in life.

Hell, I've treated it as a filter in the past: the mindset that leads a company to be unyielding on noncompetes is a signal not to work for them in the first place. That a noncompete is unenforceable in some jurisdictions functionally only means, for the overwhelming majority of tech employees, you aren't finding out how much they think of you before you sign on the dotted line and quit your other job.
