You should still stop smoking (for your own good) but that alone won't change the world.
Taking climate change as an example: 100 b-corps going carbon-neutral aren't going to offset the damage Exxon causes to the environment.
You can say we just need to wait until consumers change their behavior and let the market sort it out, but isn’t that exactly what we’ve been trying and failing to do? At this rate it’s all but certain that climate change won’t be solved via market solutions.
What’s better is forcing the bad actors to stop doing bad. Fighting to pass a carbon tax regulation or a green new deal is what we need, and bandaids like b-corps are often a distraction that tricks people into thinking we can consume our way out of the problem.
Charters can easily change, anything can be reincorporated at whim anywhere.
Also its typically just Shariah-Compliant investing rebranded for an Islamaphobic audience. S&P has a shariah index right across the border in Toronto Stock Exchanfe since forever while similar enterprisers push B-Corps and Public Benefit Corporations domestically as if they’ve “figured out” the code to sustainable for profit ventures through charter. Shariah in this context is very compatible with what these kind of investors and consumers are looking for, but they don't know it as they probably conflate it with human rights abuses.
People are just gullible, hope I unpacked that enough.
