Plausible, though I believe prey is stunned with infrasound.

I think infrasound could be them stomping or hitting the ground with their fists to generate a thumping noise, with prey first being stunned by the decibel level of the thumping, and then stuck in a vulnerable trance by the psychoactive alkaloids in the pheromones

Well inaudible sense of dread, nausea, disorientation is being reported which are all syndroms of infrasound attack: LRAD and 'Havana syndrome' effects are exactly the same. I think it's their sheer size and complexity of vocal cords allow for infrasound attacks inaudible to human ear. Many animals use infrasound for communication and few predators, like tigers, use it as a weapon. A smart ape with weaponized pheromones & infrasound would indeed be a formidable foe in its natural habitat even for humans reinforced with modern technology and training. There's precedent to infrasound being used as a weapon: tigers and jaguars use it, many tamers and naturalists reported sense of dread and nausea when being in territory of big cats. Are there precedents for poisonous or psychoactive pheromones in animals? I know gorillas emit aggression pheromones but I don't think their effects on humans were studied.

Is that you, Bob?

While I don't doubt that he visits, I'm not him. I just watched all his vids multiple times and find arguments in them extremely compelling. Bob always tries to draw parallels with other precedents from biological world and that reinforces his theories.

When you put 'living fossils' and species that 
 remained unchanged for tens, hundreds of millions of years to this day in a perspective - extinction of bipedal hominids with fossil as recent as 5MYA - 10KYA, doesn't sound guaranteed at all. Especially with how limited human habitat is, we mostly live on coastal plains.

When you consider budding new science field of bioacoustics and how humans themselves weaponized its findings as infrasound weapons - suddenly 'magical' abilities of Sasquatch sound more realistic.

Humans and great apes react to pheromones, with gorillas specifically reported to have strong rotten smell when they're building up for aggression. Bigfoot reports of strong smell of 'death' make sense here too.

The saggital crest on large males - Gorillas and Chimps, especially Bili ape, have it to mount powerful muscles.

'Big foot' is thanks to midtarsal break that all great apes but humans have. Same with 'leaning forward' walking position, without arching feet like ours, different locomotion mechanics are a given.

Bob just lines up all of these, and many others, arguments really neatly in his videos. This is the kind of presentation you need to have if you're out to convince people and get traction behind topic that interests you.
