@PoCampo It may be used heavily in enterprise and large corporate messengers (Nintendo Switch, Whatsapp, Zoom, etc.) but I suspect they meant "overlooked by most casual technologists".

@PoCampo It's also frequently dismissed as "it uses XML and therefore must be bad, let's evaluate something else" and despite the fact that I personally see that as its major flaw, it's still often the best tool for the job and this kind of "overlooked" might also be what they meant.
