I used to work in IT, and I would say that anyone relying on cloud services for sensitive data is not a professional (even though all the "kids" do it - hey, we live in a world where a 100k hack is solved by "printing" more tokens - not serious at all). This is my opinion, no doubt about it, but with the cybersecurity issues we ALL know about, I never ever had a client's sensitive data in the "cloud". NEVER! Not even backups. That's all done ON SITE, and multiple locations if the data is extremely sensitive.
To be honest, everything I've heard here on his part sounds extremely "amateur". Sorry, but that's my take on what I've seen him say (and how he's said it, etc., etc.).
