However in January the entire sales team removed them after apparently a customer reacted negatively to the inclusion. Which lead to other external facing teams removing it to prevent the same issue. Most people have removed it from emails, and honestly many people just don't seem to care, and HR doesn't seem to be enforcing it.
Mandatory pronouns are a pure shibboleth in the culture war. Trans activists don't want it. Anti-trans activists don't want it. The only people who want mandatory pronouns are the folks wanting a cheap signal for how much of an ally they are and an easy way to identify and ostracize people who aren't in-line with their politics.
If someone is really okay with all of them and wasn't just saying it to be disrespectful, then it's fine. If they said it just to devalue someone else who did care (but really cared themselves all along and in no way would actually be okay with it), then it is wrong.
