It's a term that describes how people feel to pressure to conform to a certain popular view and they are hesitant of speaking their opinions. Depending on the context, they might be worried about being excluded from a social group, losing friends, losing social status, or getting literally cancelled (in the case of a celebrity in the entertainment industry). The term "cancel culture" broadly describes this feeling and it's not related to actual consequences (if any).

At least this is how people use it. You could argue it's an inaccurate term since there are no actual cancellations in most case. But the prevalence of this sentiment is still noteworthy imo.
