Very disingenuous as they've release many products over the years. With each of these releases they've moved the development of the Safe Network forward. Simply take a look here - https://safenetforum.org/c/development/releases/76/ A test network was just closed and they'll be fixing a couple of things releasing another ASAP.
I've still got some learning to do, but the whole kademlia dht thing is a pretty interesting middle ground between the IPFS approach (not enough redundancy) and the blockchain approach (too much redundancy).
I'm not sure it's ideal because if the network partitions you're going to end up with a more or less random assortment of data in your partition. Better for the biology data to end up on the partition with the university that specializes in that and the physics data to end up nearest its users as well. (This may be handled at a higher level, but I haven't gotten that far yet.) Nonetheless, I'm glad somebody is exploring the design space.
I'm not saying they haven't been doing things, but the big decentralized Internet they touted from the beginning still doesn't exist AFAIK.
When I can host a website and have it stay up indefinitely with zero maintenance.. then I think they have something.
I'm sure it's an enormous amount of work and I did buy some coin so I don't mean to be disparaging, but I stopped tracking updates after a couple years because it's all been technical mumbo jumbo and they don't seem to be moving the needle. They've had many "test networks" over the years.
Good luck!
