training employees to avoid using certain words in office communications

Is it not standard practice at most large organisations to have style guides and recommendations from HR on workplace culture?

"Among words and phrases that Google employees were trained to avoid were “market share,” “scale,” “network effects,” “leverage,” “lock up,” “lock in,” “bundle,” and “tie.”

“We don’t ‘lock up’ or ‘lock in’ our customers,” and “we do not ‘leverage’ anything,” Google told employees.

During a 2011 training called “Antitrust Basics for Search Team,” Google also directed employees to “avoid metaphors involving wars or sports, winning, or losing.”

The “don’t use violent or competitive language” instruction seems pretty common in larger workplaces, purely from my own experience.
I think it’s pretty funny that “bundle” and “scale” were included though.

I’m not sure this is particularly persuasive as its own argument, and I suspect it’s the deleted communications that hold far more relevance.

If you really want to investigate Google’s monopoly, I would suggest looking into the events/parties their ad account managers host/attend.
