An IT culture that's built their budget and staff around managing a datacenter with on-premise software lacks incentive to support cloud implementations.
Whilst true, the on-prem based implementations are usually insecure and manual as fuck, which largely means the IT function simply stopped learning.
Also, the move to cloud is largely driven by said IT teams failure to deliver much, you could a the CRM on-prem, but we know they'll likely take a few years to fail to deliver it.
