I guess this is anecdotal, but counterexample. I had COVID twice. The first time there was extensive contact tracing performed by the county. The second time, there was basically nothing. Contact tracing in my area stopped when Omicron took over.

Both you and the commenter you're responding to are making the point that contact tracing now seems not to be actively pursued. Both accounts contradict the article. To that extent, you seem to be in agreement.
