The biggest pro of decentralization is censorship resistance. You can compute, store and transfer data and disregard authority or oppressors. This is why torrents worked. They allowed people to share media even though it wasn't legal. Then people found a way to make a more performant centralized alternative and it is so much easier to use that most people now are willing to pay for it, even though free torrents still exist. Email and git are also prone to centralizing forces. They are both decentralized protocols, but everyone ends up using Github and Gmail anyway, and not actually using them in a decentralized way. If you are sending "sensitive" emails or are sharing code for a dark market, email and git will be useful if you steer clear from centralized hubs. Bitcoin is the same thing. Some people don't want you to send money to Wikileaks, so Bitcoin is the first time we can now send money online and disregard who the authorities tell us we can or cannot pay. With Ethereum, decentralizing computation is an open question. Do we not already have censorship resistance in computation? Is anyone preventing us from running code? Is Tor not sufficient to run shady decentralized apps? I don't know.
