Previous postdoc supervisor removed my name in the published article
It could be that your co-author attempted to reach out to you in order to get your permission to use your name but never got a response, i.e. old email/ not known address, ran out of time and had to publish without your name.
I would advise getting in touch with your colleague first in order to establish what happened before using the nuclear option.  It may be your colleague will assist in amending the published article.
