Re: No surprise here
I blame it onnthe execs that thought or think cloud is a wonderful thing. Then they get into the details and decide "oh, not so good as I thought" and stall or can it (in many cases for good reason).
One of my friends works at such a company, they wanted to build a big cloud practice (I knew it wouldn't work before he even took the job), he was hired to build and lead a cloud services group. 6 months later those prospects were canned and he has a backoffice role biding his time until his next gig).
It's just too big of a change for many orgs. Ends up being too expensive and/or fails in one of many ways because people think they can save some cash by shifting shit to opex.
