It’s a good point.
For me it does come down to ethical investing, to an extent. But it’s a tricky one.
Taking this one aside, I for example won’t invest in a gambling company. Even though people voluntarily gamble, I just feel like I’m making money from someone losing money or potentially a bad habit. Having worked in banking I’ve seen the effects. But that’s just me personally. I even questioned whether I should invest in a tobacco company.
That aside, most organisations have a Corporate Social Responsibility and know that investors make money if they grow their customers, but if for whatever reason they do something that customers may not like (not arguing for or against airbnb here) then it can impact everyone.
Company image sometimes isn’t as far removed from the bottom line these days as before, so they may have thought it important to address both.
