#2> The bamboo strands are placed in a massive industrial press and compressed with a pressure of 2,500 tons.
I wondered if this number was a typo. Quick research shows that presses can produce tens of thousands of tons of pressure. [1]

#3This particular post is about making plywood sheets out of raw bamboo. But there is also work happening on mass timber applications of bamboo. For example a company called "Rizome" (https://rizomebamboo.com/) is working on LVL and LSL bamboo panels. One of their founders wrote a post about structural applications of bamboo last year (https://medium.com/rizome/bamboo-skyscrapers-eded5b234726).

#6I wonder what kind of glue it uses, it's used in all of the processes

#7I would love to know if there are any "hobby" communities for "doing things" with bamboo.
I'd love to pot some of the fast growing stuff at home and harvest it to muck around with.

Seems about right; 1000psi assuming a 4x8 foot sheet, roughly.
Bamboo is a -somewhat- soft pseudo-wood and can deform enough under that pressure to compress into the sheets they're describing.
(for reference, I've operated a 10kton press at a previous job, which was roughly 30 feet high + underground hydraulic lines. I don't know how many presses of this scale are even left in the US)

Formaldehyde. It’s actually pretty unenvironmental. Because it uses formaldehyde and other chemicals, you can’t sand or refinish bamboo, and the dust is extremely hazardous.

In the places where bamboo grows natively, it is used extensively, but typically not for long-term structural applications as bamboo is susceptible to rot and insect infestation.
But it forms decorative elements: fencing, window blinds, or window framing[0]. Also tools like sumisashi (an ink pen) or poles for carrying things. Even scaffolding even on high rises![1]
