Boycotts aren’t going to kill a company. They are to influence them.
I did boycott ChikFilA when it came out they were supporting homophobic asshats. And once they announced they were dropping those charities, I stopped boycotting.
I use CVS over Walgreens as long as I can get my prescriptions at CVS due to Walgreens stances against women’s health. If Walgreens ever cleans up, I would happily use them more often because they are more convenient and inexpensive for me.
I only go to Shell gas stations as a last resort because they blast ads at you while pumping gas.
