None of grandparent's reasons are smoking guns, they're just "things that would fit the conspiracy if it was a conspiracy". The probability that it's fake given those reasons isn't high enough (like by Bayes' Rule) to deem the whole story "definitely implausible".

That seems like something you would definitely overhear your boss talking about if you also heard that they were trying furiously to contact Google.
The best reason it's maybe a conspiracy is that Google would be hesitant to "ban a whole company", but who knows, maybe if the perceived ToS violation appears severe enough (they didn't know OP's persistent piracy was a joke) Google has zero tolerance.
