In all seriousness, though, was the idea that "If it's also on PC it's not exclusive" always been a thing? Console games have gotten PC ports for over 20 years now. FFVII was released on PC less than a year after its release on PS1, but I don't recall anyone saying that FFVII wasn't an exclusive anymore. Same for FFVIII, MGS, Tomb Raider II & III, and Driver. All got PC ports at the same time as or less than a year after the PS1 version was released.
Personally, I think that if a game releases on one console but not any of the others but does get a PC release—a "console exclusive," to use Wikipedia's classification in games lists by platform—it should be considered "exclusive." Exclusivity doesn't have to always mean full exclusivity. If you're a console-only gamer and can only buy a specific game for only one of the three console platforms, then it's an exclusive.
