I've seen plenty of badly argued Chinese room debates- there is certainly a lot of bad arguments in those styles. You seem to interpret them as saying all of those arguments are bad, which is a fair interpretation, but I think their point stands if it refers to the nonsense versions of those arguments, which are everywhere on social media (hn, reddit, X, etc).

By the way, I think referring to the burden of proof in discussions like this is likely never to improve the debate. All sides will simply claim the burden is on others for one reason or another, most of those reasons will be flawed- requiring discussions on those flaws and now we're even further from the actual points we want to discuss. I've just never seen it produce a fruitful discussion.
