I am always amused how much Thaco gets under the skin of grognards. Thac0 has been the butt of jokes for 40 years. Older players found it inferior to the attack matrixes of 1e, newer fans hated how intuitive it is to add and then subtract for every hit. Upwards AC was a considered for 2e (and kiboshed for compatibility) because of how nonsensical it was. People made Thac0 jokes when Thac0 was in it's prime. But WotC had the gumption to mock the second most mocked mechanic in D&D history and every grognard already nursing a grudge found their knickers twisted and their pearls clutched in fake Kabuki outrage that WotC was impugning the honor of AD&D and the people who played it.
Honestly, even if WotC was making a light-hearted rib at a long mocked mechanic rather than a biting criticism of grognard players as grumpy fools, the fact the grognards looked at Thaco and saw themselves in him says more about the community than WotC. So I say if the clown shoes fit...
