Centralization is prone to corruption... 2008 financial crisis ilustrated it very well worldwide...
Decentralization, while having a bigger overhead, also benefits from a bigger pool of contributors...
Example 1 - mathematics: if the europe-mathematics did not cooperate with other world-mathematics, they would limit their knowledge to only european findings, which would leave them reduced compared to the worldwide mathematics investigation
Example 2 - wikipedia: more updated and complete than many classic-editor-encyclopedias that were sold before wikipedia was made.
These is very good news overall, taking into account that we are now in the first-stage-of-adoption of bitcoins, where the most important is to spread the info about bitcoins and increase its usage.
In a later stage, when bitcoins are more diseminated and people feels bitcoin more "domestic", then there will be a interest for "personal-wallets" and "business-wallets", which may be hardware-wallets, or multisig-insured-online-services...
TLDR; this is a good-first step toward bitcoin adoption, further later will be another step towards personal-wallets.
