Boycotting is not cancel culture, IMO. It's one thing to vote with your wallet, or vocally protest against a company. It's another thing entirely to go after someone personally and attempt to ruin their life for something they've done to offend you. I suspect that's the problem most people are thinking of when they use the term 'cancel culture.' Like Justine Sacco. Totally horrid leveraging of the power of the Internet to destroy an individual.
