To put out something that is opinionated, one needs to risk others being critical of their opinions. People who are always worried about having the “right” opinions will rarely risk stepping out and doing something different.
So all the safe boring stuff that gets released is just a defense mechanism, where people avoid going too far in and direction to avoid being accused of having bad taste. Ironically, this creates its own lack of taste. This lack of taste is usually just ignored as boring, rather than attacked, so it feels safer.
