Agreed. Also, censoring is a lot of work! Sure, some stuff is extreme such as racism, sexism, etc. that most reasonable people would agree should be censored. But where do you draw the line? Choosing to censor means defining what is allowable and someone will always disagree with where the line is drawn. I sympathize with community moderators (or lack thereof).
For me at least, choosing not to censor and endorsing something are completely separate.
Great list! If you already have the Raspberry Pi devices, great. If you were going to buy some, I would look at thin clients instead. Low-power, cheaper, more powerful, can use real hard drives instead of SD cards or adapters, and x86 instead of ARM. I have an HP T630 I like but I hear good things about the Dell Wyse 5070 too.
