But the underlying question about whether not-joining and buying from competitors is also interesting. We all know consumer boycotts work. What he is asking is whether that can be transported into the investment world.

As others replied, there are many more investors than customers, and besides it is a largely anonymous operation, so it is much more difficult to affect a company by making it easier for their competitors to raise capital. I still think it is interesting whether things like Pope calls for people not to invest in arms and oil has had any impact.
