This is a bit thin to be drawing any conclusions. Only what one person claims. Has this happened to anyone else? Might there be another reason (that they're not telling us) that this happened?
My son, an 18 year college student with no legal issues ever (except a speeding ticket) - had his Global Entry revoked last year. For no apparent reason. We filed an appeal and are waiting for a response. From everything I've read on it, it seems it could take upwards of 18 months to get a response. But per the article you linked, it seems that less than half are able to get it reinstated. So I'm not really hopeful.
