Those being in the list doesn't mean that's what they're looking for. Take a look at the database of extensions, there's far more extensions that don't seem limited to any particular group. The author just called those out specifically because they're perfect for implying nefarious intent.

The claim I replied to is “They try to profile for things like political beliefs”.

I wasn’t contesting that they query extensions that can be used for that purpose, or that they use query results for that purpose, but indicated that the fact that they make such queries doesn’t necessarily imply that they try to do such profiling.
