A backdoor would imply some sort of external control I’d think…

Yes, technically a backdoor listens: csrc.nist.gov/glossary/term/backdoor

Being able to command a device to send you info or perform tasks is different than the device sending info of its own accord.

In this context, where it’s implied to send without the owner’s knowledge (ignoring the fact it’s documented), not really. The article screams “gotcha!” when in reality it didn’t, so they’re trying to backtrack and downplay their initial response. But I do appreciate their update, it’s just got a PR spin to it.
