Edit: You know initially I agreed with you, then I realized that your suggested comment accomplishes essentially the same thing.
Anyone would be able to infer from my comment that I don’t support the way that billion dollar companies are allowed to abuse their workers. It implicitly supports the idea that they should not be allowed to. Your suggestion contributes about as much to the discussion as my comment does, and to say that they are meaningfully different implies that people can’t interpret sarcasm.
Both my comment and your suggestion are saying something obvious, but so is the article. That’s the joke.
