No, you read it right. I just misunderstood the post's message as "these exploits will enable more supply chain attacks". I'll probably delete my comment since it's debating a strawman. It is absolutely right that these exploits might enable these attacks to have a larger impact. I still don't think that I agree with the message since a malicious npm package already installed can get its payloads from a C2 server, it doesn't need an npm update.
