> Many geek hobbies like 3D printing and home automation are becoming full of unnecessarily smug evangelization if you're not using hivemind approved software and tools, even if it requires a lot more work to do.

A mix between gatekeeping and tribalism. Reasonable people realize that others who want to enjoy a hobby do not have to do the hobby the same way as they do, or make the "right" choices.
