Most customers don't care the only reason it's a real issue is Twitter users run the marketing department at a lot of companies and they are incorrectly convinced people care.
How much is "most"? What data do you have? Plus, even if ~20% of customers care and only half will boycott, that's still going to have an impact on the company's bottom line.
If that were the case why is Twitter ad spend in the low single digits for most companies.
