>>What are we alarmed about?

While I think the study has some major deficiencies addressed in other comments, if it was true, the alarm for me would be that Wikipedia has clearly become politically partisan in many area's and topics, including some that would intersect the law

Wikipedia is hardly a "neutral" site of just facts

[haswell]

Do those have topics have anything to do with the class of Wikipedia article mentioned in the study?

I’m not saying there isn’t bias, but the existence of bias in certain controversial subjects isn’t necessarily evidence that articles about cases are subject to the same kinds of issues. I’m not saying they’re immune either, but it’s not clear that the two are related.
