How is it decentralized if step one is to upload the file to the central file-sharing service?

I think you're describing one such portal.
The magic is that any file you upload to one portal is instantly (within about 5 seconds) available on any other portal. The portals themselves aren't running any sort of DHT or federated network - if you upload a file to a portal, then all portals go offline simultaneously, then you spin up a brand new portal, that brand new portal will still be able to see the file you uploaded.
From "looks interesting" to "close tab" in one word.

Not sure why you implied there was any need to look further into this. It seems to be based on proof of waste.
You seem to have a very definitive and final opinion on proof of work - would love to hear your opinion on this paper
