I don't think you can claim that. It's the fate of most popular systems. they end up being poorly explained in elevators or adopted based on a blog article rather than investing the few hours or days or weeks to understand what made the process originally successful. It's so common we have a term for it: cargo culting. I don't think you can fault agile for the tribally-spread BS most places do today where points == hours. If anything, you can maybe fault it for seeming a bit too familiar and simple when there are a few important nuances.
