what do you mean by "content-centric-networking"? perhaps I have some reading to do.
the "allure of large companies hoarding all the data" might be a factor independently though. I personally believe a proper content discovery service is key to any form of decentralisation, and that is, as far as I can imagine, highly dependent on centralised entities amassing and then processing large amounts of data. I mean we sold our data to Google and in return got the current decentralised web where anyone can make a website and get traffic if the content is good enough (or SEO-hacky enough).
