The article is written great and was enjoyable to read. I do have issues with how it is focused on NFT marketplace to the detriment of explaining what the real benefit of the blockchain/crypto is. Which I am going to try and explain to the best of my ability. Here goes. The article omits to mention that whatever is stored in the blockchain is immutable. This means that there is not google or Zuckerberg behind it all with ability to actually change what's on the chain as this is not possible at all. Instead the author focuses on the ability of OpenSea to remove things from their marketplace and also how it uses centralized apis to get the info. This, while true, is orthogonal to the immutable ledger use case which is still true.
