It's a real red flag that he plays stronger moves after the browser window loses focus. I'd argue that's much less circumstantial than anything else so far.

I made this a while ago.
Or just use another computer.
and yeah you could argue that if you're not into web dev it's not hyper obvious that websites are able to know when you lose focus on them, but I'd argue that it is fairly obvious. there are indications that should make it clear. facebook flashing notifications in their tab title until you click on them, to take a simple example.
I imagine there is one chess cheater reading this that will use your repo soon.
They can really only think in front of them. If I put information into this program, I get information out. They don't think that applications can monitor their own meta-state. Or the state of other applications.
So I'm not terribly surprised that he thought running the engine in another browser window would have been sufficient. He might have even had it open in "incognito mode". And since it's incognito, it can't be detected, right?
When chatting with a customer support it's quite apparent the csr is involved in many chats at once; wouldn't it be quite taxing for them to have to monitor not just the responses but every keystroke of the people they interact with?
these are things I’ve noticed without any experience of autorepair beyond “here’s how internal combustion engines work”
See what I mean? It's a bar that most people don't cross.
also knowing how an internal combustion engine works is not equivalent to knowing that html code goes in angle braces. it’s more equivalent to knowing that you need to use a certain type of wrench when working on a certain type of car (I don’t know if this is actually true because I don’t know how to fix cars, but it’s more equivalent)
Agreed, and I would guess that is the extent of what people do with that observation. They see it, and have no clue why or how or what that means. Is it only certain browsers that do it, or does it depend on if it's a phone or laptop? Maybe it's a AT&T service feature on phones now? Or maybe just iPhones do it. Maybe it's only on previously visited sites? Or maybe it's a virus or a scam of some sort.
People with no frame of reference see things very differently. It's a magic box.
If he accidentally showed a picture of his second computer on the same desk during e.g. a stream it would be akin to guilt admission.
