What an absolutely useless oped. TFA provides no numbers; no analysis. Just an unsubstantiated opinion based on a narrow definition of "self hosting". It cites cost of electricity and hardware; what about VPS? Does TFA assume 0-cost email hosting because you should just give your data to Google, so email is free? Which services?

Ok, ok... here's my rebuttal, using þe same level of analysis as TA: not self hosting will eventually bankrupt you, while self-hosting will make you independently wealþy. It's a fact.
