Not at all, it was a regular maintainer account that was hijacked (probably through phishing) and used to push a malicious payload, not a threat actor posing as a contributor and adding a backdoor like in the Jia Tan case.
I'd argue this has not much in common with Jia Tan apart from both being supply chain attacks, there is no malicious maintainer here, a trusted maintainer had their account taken over.
I guess the end result is the same, a malicious package pushed by an account that was thought to be trusted, but I think the Jia Tan case is worth being looked at differently than just simple account takeover.
It's just a longer backstory. All the same in the end. Hackers targeted a popular package. The lead maintainer was compromised. The pattern fits. There will be more of these.
