EDIT:
TL;DR from Wikipedia for the lazier of us:
In the United States, a benefit corporation or B-corporation is a type of for-profit corporate entity, legislated in 28 U.S. states, that includes positive impact on society and the environment in addition to profit as its legally defined goals. B corps differ from traditional corporations in purpose, accountability, and transparency, but not in taxation.

By the way, they have a lovely FAQ:
"How did Etsy get its name?
The true origin of the word “Etsy” is a mystery known only to our founders. If someone asks you where the name came from, just make something up. That’s what we do."
The real point is that shareholders can't force the company out of general compliance. Meanwhile, managers retain considerable latitude in determining how they will remain in compliance as the company grows and evolves.
As long as founders and managers run a profitable company within these parameters, they - and their investors - will be fine. Indeed, they can, in theory, pursue the kinds of opportunities that companies totally beholden to growing their quarterly returns have to pass up. What they don't have to deal with is some short-term "investors" who want to extract a large hit of quick cash before leaving the smouldering ruin of a once-decent brand in their wake.
You may say this is a broken system, and for many B2C companies it can be. This is why I think that the benefit corporations are quite possibly one of the single best things to happen to corporate business in almost a century.
It allows a company to focus on a mission statement, and protects it from shareholders who only want to focus on profits.
