This isn’t a binary answer since it depends on the target and how many people are actually doing it.

For example Disney+ boycott worked since an actual lot of people participated in it, it’s also easy to cancel a subscription, but on the other side, Hogwarts Legacy’s boycott didn’t do shit because almost no one cares that much about sending a message, and there was no substitute for the fantasy of living a virtual life in a magic school, yet.

While politics boycott need a large enough mass of people to accomplish anything, and this my may ruffles some feather but, violence is often needed just like what happened in Nepal.

It can since it’s much cheaper than video and games thanks to the small file size of songs.

Very few people even know how to put songs on their phone to play locally, imagining trying to teach them how to host their own streaming on their computer.
