Storj, Maidsafe, Sia, and Permacoin
(and any other decentralized file system that pays to store a file instead of only paying to serve the file) are all
provably scams.
He seems to be saying (among many other criticisms) that the economics of decentralised cloud storage systems can't work, and storage providers will end up using dedicated servers and smaller opertions will get shut down by their ISP's. He's a wacky guy, but not a light weight thinker. Does he have a point?
No, he doesn't have a point, because he made no point.
I am not a Sia dev but it is hard to take his comments seriously. He makes some hand-waving claims that Sia is prone to Sybil attacks, without proper analysis of how. He then
concludes that Sia is therefore a
provable scam, which demonstrates that he is incapable of logical deduction. For me, taking anything else in his post serious is therefore an impossibility.
In order to make these claims, you need some demonstrable proof of your assertions. I am not saying a Sybil attack can't be done, but I disagree with simply taking it for granted.
He moves on to some legal justifications for why Sia will be limited to ISP user clients which are simply not true. There is no reason why a commercial entity could not provide storage on the Sia network, even if they host illegal content, as long as they take steps to remove illegal content and block nefarious users. Dropbox does it. Google does it. Why can't Sia storage providers? Just because there is no central authority, that does not mean there can't be policing and enforcement of the rule of law.
