Background
I work in an IT consultancy company of about 200 people. As in many other companies, we work on multiple projects, with short deadlines, with a lot of pressure, both from internal managers and from clients, etc.
Last week a coworker (B) of another team got angry during a call over a person from test/QA department and said in an angry tone “You are not paid to think, but to carry out tests”. The heart of the matter was that the main tester on the project was flooding Jira tasks with hundreds of comments with suggestions, “I think that”, “I was thinking about”, “I suggest this development”, etc. These unsolicited comments are many times only loosely related to the bug. Because of internal policy, only when all comments are addressed, the bugs can be closed, so this tester was tasking in hostage and delaying an already delayed project.
In the call there were: B, other members of the development team, the project manager (and B direct manager), a higher manager, the tester and some of his team and the tester direct manager: nobody said anything about that sentence.
Questions
We discussed about the sentence between us and the widely accepted thought is that it is a passable sentence under these or similar circumstances, but it is preferable to limit its use. I also spoke with some friends from different industries/fields that instead said are all convinced that the sentence is not acceptable in the workplace. Whereas friends from IT generally agree with our conclusion.
Is this an acceptable sentence under some circumstances? It is always wrong in the workplace? Could it expose who says it to any consequences?
PS: there are no consequences on B for this sentence and also unsolicited comments by the tester stopped and all bugs are closed (usually directly by the tester manager)

Many thanks to everybody answering my question, I had the opportunity to read a lot of suggestions and interesting points of view.
I also had a quick chat with B yesterday and he explained that the direct manager of the tester sent an e-mail apologizing for tester's behavior. This manager also took the place of the tester in the project and all bugs are now closed and the product released. Finally this manager moved (demoted?) the tester from a position on test/QA team leader to a position of simple integration tester on another project.
