Look for a quid pro quo from some government or uniparty entity. My bet is SimpliSafe would not have done this without one. Follow the money.
My bet is they simply caved to Masshole social pressure. I have no inside info, other than living in Taxachusetts.
Being Hahvard MBA's, I'd have expected them to have the intelligence to relocate to a more favorable venue before starting their business venture.
But hey! Relocating is work. Otherwise, I'd be somewhere else. But, I'm lazy!
