People boycott things all the time for all kinds of reasons. Some people boycott Israeli businesses due to the Israel/Palestine conflict, other people boycott MyPillow, and others boycott Chik-Fil-A, or more recently Budweiser. The outrage here on HN is a bit annoying, considering this used to be a fairly balanced platform.
As a consumer, boycotting a business is basically the only recourse for whatever grievance (justified or not) you may have which happens to be outside the purview of the law. Or is boycotting not petty only when your tribe does it?
But if many people think you are being petty/bonkers/anti-something-they-care-about based on why you are boycotting particular businesses, that might cause you some trouble.

There are certainly some boycotts I don't participate in, but respect the decision of those who do.
Boycotting is petty when people think it's petty (pettiness is an opinion, not an intrinsic property of something). If you want to talk about "tribes", sure, maybe a particular "tribe" thinks some particular boycott is petty. That's life.
I know if I was hiring for something and found that post, that'd be an instant no-hire from me.
