Nope, believe it or not it is dirt cheap to run one of these.
It really depends. It would not surprise me if lemmy.world needs to buy a terabyte of storage every month just to have enough space for all image uploads. That's possible when you can just use a single hard drive and put it in a server at home, but if you use hosting and/or want redundancy that can add up quickly.
We’re not talking about the ones where every person decided to sign up to though.
