Even in taste, some things are objectively awful -- eating shit for example.

Whether some bizarro outlier likes it doesn't matter, the statistically significant majority doesn't. So, it's not that shit is subjectively good or bad taste it's that said persons are objectively weirdos.

In other fields things are subjective, but people who know better have a canon, which is a more objective ranking. E.g. how Vanilla Ice is worse than Bach in substantial ways, even though some (even many) might prefer the former.

Programming languages are also part of computer science, which has some downright objective criteria too.
