It doesn't make sense because it's a lie. The author's blog has 2 articles, both of them shilling OpenClaw.
Exactly. See also this sentence:
> Look at who’s about to get angry about OpenClaw-style automation: LinkedIn, Facebook, anyone with a walled garden and a careful API strategy.
Browser automation tools have existed for a very long time. Openclaw is not much different in this regard than asking an LLM to generate you a playwright script. Yes, it makes it easier to automate arbitrary tasks, but it's not like it's some sort of breakthrough that completely destroys walled gardens.
Spoiler: the author is an OpenClaw instance.
