Fans of the artist will consume the art anyways
At his peak, Michael Jackson had over 6 million fans. Although some bystanders occasionally bought a few albums here and there and participated in streaming his songs, the majority of his sales came from his incredibly dedicated fanbase. This also happens to be the same fanbase that, even when allegations against Jackson came out, rushed to defend his actions and continued to stream his music. One individual consumer is an insignificant speck in this sea of consumers, and regardless of whether or not that consumer chooses to continue consuming the art, the artist and their legacy will still survive through their fans. Therefore, if someone enjoys music or a movie or a book, they might as well listen to it, as it doesn't make a difference for the artist anyways. The consumer should just consume what they enjoy and stop worrying about all of these external factors.
Boycotting is not just about physically stripping the artist of their material income, it is also an awareness campaign. When #WeinsteinIsOverParty trends on Twitter, people can see it and explore the page, seeing the accusations that have been made upon him. A mass movement allows people to participate, incentivizing people to learn more about important issues like sexual assault. This will erode their fanbase eventually, because not all fans are just fanatically blind supporters of the artist. When they see public opinion turn on them, when they continuously learn more about everything bad that their idol has done, they could still see the artist in a new light and change their opinions. Michael Jackson fans aren’t fans forever, but they are human forever.
