The author never actually articulated what his beef was with Netlify. So yeah I think you're just as confused as the rest of us. Apparently Netlify was supposed to become Heroku, but Heroku is bad, but Render (which is... Heroku with a fresh coat of paint) isn't? I dunno.
Render seems to have autoscaling with a reasonable round-robin load balancer [1], whereas Heroku only has autoscaling in (expensive) Private Spaces [2] with a dumb load balancer [3].
