It's going to be an "if," not a "when." The percentage of users who want to manage their own cloud is vanishingly small. If people are sensitive to the risk of handing over their data to a trusted (well, trusted enough) corporation with a reputation to lose and money on the line, how safe should they feel putting their data on a cloud they manage, essentially stacking themselves up against every Joe Random Hacker on the Internet without the benefit of a Google, Microsoft, or Amazon SRE team to keep the shields up and the lights on 24/7?
The risk surface for self-hosting is higher, on multiple axes, than cloud-hosting. Hosting your own cloud is the "I don't trust auto mechanics so I'm going to become an auto mechanic" approach and most people have neither the time nor the talent.
