You need to stop worrying about the cloud and focus on being agnostic to things like VPNs, on premises and so on. (Also SSO mechanisms). Any cloud needs to be optional. If you can make it easy to deploy on a private cloud where everyone accesses it via corporate Google accounts but also deploy on prem (say containerized) with Active Directory integration you will cut a lot of noise.
Game artists will increasingly not trust the cloud as it is where their data goes to train AIs, but more pressingly a large proportion of asset development is done where the network (and electricity) is surprisingly flaky.
To be specific I have been involved in several situations where we were not allowed to mention things in email due to it being cloud hosted, and those restrictions were imposed by companies that are themselves cloud providers. That is the kind of level being discussed.
