Earlier quoted context omitted.
I don’t see this article showing that. They query for extensions that could be used to do that, and that likely already is illegal, but those queries could solely be used to uniquely identify users (grabbing more bits makes it less likely to get collisions)
The list of queried extensions includes things that would be used by particular religious groups, and people with certain medical conditions.
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.
