I don't see how their analogy is stupid. Aeropress and french press are pretty similar from an "enthusiast coffee device" perspective. Lots of room for variability in grind size, coffee choice, and specific brewing technique with both methods.

Aeropress is a brand, one I've never heard of. It fits in the Linux ecosystem (maybe as one of the Red Hat flavors?) but as an analogy it is simplified. Linux is so much bigger than that and there's everything from LFS (grow, grind and brew with tools you've sourced and put together yourself), to Android (plain old drip machine). Reducing everything that's the Linux ecosystem to a niche brand of a specific type of coffee maker is dishonest.

I use a french press myself, and never heard of Aeropress. My machines all run Debian with DWM and I never have any problems. My non-technical girlfriend is fine on Debian and doesn't really know the difference. She did mention how fast her laptop boots though.
