Does writing,
Former technologist at Foobar, Inc. and Hello, World Ltd.
have a deprecating tone to it? Say, as opposed to,
Previously a technologist at Foobar, Inc. and Hello, World Ltd.
That is, is former a word reserved for describing something (a state or position) once held but then revoked? It seems more often used in such a light, but I'm not sure whether it's meant that way.
