It is probably the same mechanism by which people still tip generously even when they are not completely satisfied with the service. People don't want to be seen as rude and they are afraid of spoiling a probably long-term relationship. Others maybe are afraid that not giving a 5-star rating will have a disproportionate effect on the seller's reputation, and while they are not 100% satisfied, they don't want to feel guilty about bringing some stranger to potential bankruptcy and potentially making other strangers unemployed. More tech-savvy and thus more affluent people tend not to feel so strongly about this kind of thing, and at the beginning of online commercial services, they made up the bulk of the customers. Rich people can get away with being hyper-critical in their commercial relations and yet continue to be welcomed by shops. Also, as they don't get so much of this treatment, it is usual for them not to develop this kind of empathy. Someone who has never been laid off or had to wonder how they would pay the rent if they lost their job is not triggered on an emotional level wondering what would happen to other people if the business they work in floundered as a result of bad reviews.
