My hypothesis is that this is a combination of old money and class consciousness. In other words, the rich are risk averse because all they care is preserving their wealth and the working class don’t believe and can’t even imagine that more is possible.
Know your system, every part. Big cost savings are often made at this stage just discovering a shit-ton of obsolete stuff.

What you bring back on-prem must be systematically viable.
Factor in on-prem energy costs, they are not trivial.
The biggest overall factor is people and wages. Any significant repatriation project ends up needing to hire back the system administrator you fired a couple of years ago.
I see a lot of very well educated non-feral people in the UK struggling to make good wages and a ‘proper’ standard of living. I think that’s what is meant by a broken social contract ?
