I mostly agree with this. Commercial websites probably should track engagement and try to increase it. They should probably use secure http. They probably should not care about supporting browsers without JS. If they need sign in then signing in with Google is useful. There's no harm in having buttons to share on social media if that will help you commercially. Where I think the post hits on something real is the horrible UI patterns. Those floating bars, weird scroll windows, moving elements that follow you around the site. I don't believe these have been AB tested and shown to increase engagement. Those things are going to lose you customers. I genuinely don't understand why people do this.
