I mean, you can definitely get drives. I bought a LibreDrive-flashed USB 4k/UHD Blu-Ray last month, because I wanted to (legally) play UHD Blu-Ray movies on Linux — I don’t know how much longer they’ll be around, and the quality is generally higher than streamed video. But just saying…the infrastructure to use the optical media directly is not generally there any more, I think, on most out-of-box PCs. That’s an additional barrier if you want to sell the stuff in that media format.

Yeah, it doesn’t look like they have optical drives these days.
