Anything that promotes film usage...
... is a good thing in my book. Even Lomography, with it's overpriced "hipster" (whatever that means) cameras, has played a significant role in the film resurgence. I was an early adopter of digital cameras, having been given a Kodak DC40 (we're talking about 1/3 of a megapixel as I recall, with a serial interface and limited to scant internal memory) in the late 90s. I've owned a succession of digital cameras since that time and continue to shoot more than my share of digipixels.
But a few years ago I discovered the Holga, then "graduated" to a plethora of assorted toy and more serious medium format cameras. I started using my trusty old Konica TC-X again - an SLR I bought in '87 when I was taking a high school photography class. Today I've got a small arsenal of film cameras that includes everything from 110 cameras (yes, they're making 110 film again) to instant cameras old and new (like the handy little Fujifilm Instax Mini 8). So many, in fact, that I'm having to thin out my collection a bit.
Film will always be a niche market, but there's been a growing interest in the medium for the past several years. Interestingly, a lot of the momentum comes from young people who have used digital their entire lives. Then they discover this archaic medium where you don't get to see your photos until later. There's a sense of mystery and anticipation. And your pictures have a different kind of look - a look old dudes try to simulate with expensive Photoshop plugins. And, relative to the cost of buying a high-end DSLR every few years, film can be relatively inexpensive, especially if you develop your own b&w. You get a new "sensor" with every roll you run though a 40+ year old camera.
It's a shame I don't have a 3D printer. But I've already given my wife my Christmas wish list, which includes a hopeful request for a Holga 120 pinhole camera.
