Anony Mous, read slowly so you understand... Coca-Cola didn’t remove, and didn’t need to remove, the course in question. The course was removed by the third-party provider, LinkedIn Learning, from their course offerings.
All the claims about vague orders from managers are anecdotal. It is of course possible that some individuals endorsed the training but there is no evidence the course was mandatory. All the course offerings from LinkedIn Learning are available to its subscribers, including employees of Coca-Cola. This includes the course in question, until it was removed by LinkedIn Learning.
I suppose you could argue that Coca-Cola subscribing to LinkedIn Learning implies an endorsement of all of LinkedIn Learning’s 16,700 course offerings (though it is doubtful that management reviewed all of them), but aside from that, there is no evidence of specific corporate endorsement of the course in question.
