Agreed, it's a tough problem. I think Boston investors want to support Boston startups, but because of their structure/individual limitations (mentioned in the article) they can't necessarily "take one for the team" if it's investing 20% of their 'dry powder' for the year.
That said I do think startups can play the "fund us locally" card a bit.
