> When I talk to Philosophers on zoom my screen background is an exact replica of my actual background just so I can trick them into having a justified true belief that is not actually knowledge.

The cases cited in the article don't seem to raise any interesting issues at all, in fact. The observer who sees the dark cloud and 'knows' there is a fire is simply wrong, because the cloud can serve as evidence of either insects or a fire and he lacks the additional evidence needed to resolve the ambiguity. Likewise, the shimmer in the distance observed by the desert traveler could signify an oasis or a mirage, so more evidence is needed there as well before the knowledge can be called justified.
I wonder if it would make sense to add predictive power as a prerequisite for "justified true knowledge." That would address those two examples as well as Russell's stopped-clock example. If you think you know something but your knowledge isn't sufficient to make valid predictions, you don't really know it. The Zoom background example would be satisfied by this criterion, as long as intentional deception wasn't in play.
The issue that Gettier & friends is pointing to is that there are no examples where there is enough evidence. So under the formal definition it isn't possible to have a JTB. If you've seen enough evidence to believe something ... maybe you'd misinterpreted the evidence but still came to the correct conclusion. That scenario can play out at any evidence threshold. All else failing, maybe you're having an episode of insanity and all the information your senses are reporting are wild hallucinations but some of the things you imagine happening are, nonetheless, happening.
