No, shouting whataboutism isn't actually some sort of universal gotcha even if it's the new overused internet buzzword. What you call whataboutism can be called precedent or market expectations. That's even how you usually do market research: you compare a company to its peers and determine the baseline (for revenue, financials and even the percentage of transactions that are fraudulent!)
