Wikipedia was mentioned in the article and it provides a great example of a product that was built in a decentralized way. Ironically, the author doesn't appreciate that Wikipedia's success had nothing to do with Web3 or crypto. The success of large companies isn't because of a lack of technology, it is due to human nature and economies of scale and network effects. Anti-trust is the way you fix this. Break youtube out of Google, Instagram out of FB, etc...

Also, Wikipedia has shown that centralization is necessary sometimes. For example, political pages are frequently locked because people with the most extreme and inaccurate viewpoints are the most vocal.
