Seems like you don't remember the 80s, 90s or even early 2000s. Agile was a movement specifically designed to help represent the interests of development in organisations. Obviously business corrupted it over time but the industry before it was considerably worse.

MVPs exist to force business into better defining their requirements. Prior to Agile we'd spend years building something and then we'd deliver it, only for business to then "change their mind", because they've now just realised (now that they have it), that what they asked for was stupid.

Do me a favor and spend a few years in the early 2000's writing enterprise javabeans in a place doing waterfall. Then you'll understand how we ended up with agile.
