It means ones whose designs are released and licensed openly. That would be CAD files that describe how to make the components of the machine and put them together.

The benefit being that you can repair it forever because you can just give the CAD file to a fabricator to make a replacement for any part that breaks, even if the manufacturer goes out of business.

"Cheap leather wallets are not durable and will disintegrate after a couple years of good use"

As with leather, it depends on the quality. Vegetarian Shoes' Uppers definitely don't disintegrate. The longest review I saw was 30 years and still going strong. Mine are only 3 years old, but already in way better shape than my leather boots after 3 years of hard use.

You really need to differentiate between cheap Chinese companies that use fake leather to cut costs vs companies that spend more on leather alternatives because they're more durable.

Depends in the quality and thickness. There's a reason luxury car manufacturers switched from leather. If you use the good stuff made for yacht upholstery, it bifl and zero maintenance.
