More amusingly, when people refer to FAANG, they sometimes don't mean literal FAANG but more "Big Tech" or "The Big Five", where Microsoft is included (Alphabet, Amazon, Apple, Meta, and Microsoft). Especially nowadays when "FAANG" doesn't even correspond to the actual companies anymore, since Facebook call themselves Meta and Google call themselves Alphabet.
Indeed, but it is nonetheless amusing that Microsoft straight up was never considered even when FAANG and GAFA still held meanings for what they stood for.
I suppose it's a reflection of Microsoft's disasterous failures to enter the 21st century "cloud" computing world until recent successes like Azure.
