Weaker than "I don't understand what the paper says, only read a high level layman summary, not sure even what what the experiment was for, but I'm gonna piss on it anyway"?
Even assuming what you already describe, the ability to show bi-locality as a new lower bound above which locality constraints apply, is very interesting, and nothing like a strawman.
It would only be a strawman if they claimed they violated locality in general.
That is, he was giving credit as respect to the researchers.
Come on. Parent was saying what it looked like to a layman, and then asking for someone to address that and ask what was actually going on. No need to "piss on [him]".
They took an prediction of existing theory that violates a weaker form of locality (i.e. demonstrated stronger non-locality), and realized it experimentally. They also didn't invent bilocality in any case.
It rests on whether bi-locality is an empirically interesting property. And as it turns out there are some well-cited theoretical physics papers on the interest in this property for quantum networks [1], so it is likely that I am not the right audience for this press release, and a physicist might find this significantly more interesting.

They used a new kind of locality and proved it was broken too. Interesting, but not groundbreaking.
The structure of the argument is, "We stood up a strawman and knocked it down," which sounds pretty weak. Is bi-locality an inherently interesting property? Does all classical computation follow it? I don't know enough to know if I care, but press releases tend to oversell so my default stance has to be "No, I don't really care."
