I don't understand this recent pushback against agile development.

Do you really want to go back to the waterfall and V model style of development? Those are basically guaranteed failures in a fast moving industry like software development. If anything your comparison should be applied to the waterfall/V model because it is essentially central planning.

If you are doing things like building MVPs, iterated/incremental development with frequent changes and deployments to production then you are doing agile development.

Maybe it is not hyper formalized like Scrum but it is agile nevertheless.
