I don’t mind it with SaaS. Also for enterprise software, you used to pay for the license and then a support package, which basically is a subscription, on top. So there’s nothing changing per se.
Problem for partners is, that they don’t know whether they’ll stay partners and whether they’ll be accepted in the new program. If not, they cannot provide their SaaS solution to their customers.
Imagine your company gets a letter from its MSP that basically reads: “Hey, VMWare doesn’t give us information about our way forward, we may be unable to continue to provide you with VMs. This happens to all partners, so no need to ask other MSPs, as those will tell you the same. We currently don’t know how to proceed, but in three months all VMs that you have hosted with us might be toast and the only people who can tell you what to do are at broadcom and don’t give out any information”
