We need to get acquainted with the idea that free and cheap internet and cloud services will soon disappear. We are approaching crisis and actual profits will be more than the theoretical market share... So my tip, embrace open source, investigate self hosted solutions, on-prem technology and migration scenarios.

Absolutely agree with this.
Agreed about the free and cheap cloud services. I recently heard about Tahoe-LAFS. I hope to find the time to check it out soon. Hopefully by using something like that, it will be possible to spread your cloud storage across multiple providers to protect against loss with them disappearing.
