I looked into this a few years back. What confused me about this article is the blurring of custom earphones and custom ear plugs.
You can get standard in ear monitors that come with a variety of interchangeable earplugs of different sizes, and different materials, like foam.
I believe it's possible, and fairly standard, for musicians to use these with custom fitted plugs.
But this seems to be talking about the whole device being custom made which sends the price rocketing and it's not clear what benefit that adds. Is it custom fitted to your outer ear too?
I'm also somewhat surprised that the state of the art is still to take molds rather than some digital scan of your ear, surely someone is working on that?

Are there open standards for earplugs?
