> Arguments from popularity can be amusing when laden with sarcasm, but that doesn't make them valid arguments.
Informal fallacies don't automatically invalidate the argument either. Informal fallacies are rhetorical red flags: they predict problematic logic, because they're generally used in place of actual logic: but unless you're talking about formal fallacies, the argument can still be valid.
In this case, it depends entirely on whether or not you accept popularity as a valid metric for success or quality or whatnot: you're arguing whether or not the "P -> Q" premise is true or false, not whether or not the argument itself is valid. Because P is true.
