Not necessarily. There are a lot of things that folks look for when buying hosting or a support contract. For example, trust and confidence. I trust the primary maintainer of a open source project to be able to support me better than some one else maintaining a proprietary fork. In fact, the fork being proprietary means I am not going to use it when there is an open source alternative. However, I also distrust a project that is AGPL/GPL with a CLA to a corporation. If there were no good alternatives, I would probably choose the open source option to proprietary one... but I would try to find some one else to support it. Prior to this change, I would have defaulted to using Element/Synapse software, and paying Element corp for any services I require. After this change, I am looking for alternatives not only to Element corp, but to Element/Synapse the software. Even if I continue to use Element/Synapse, I am unlikely to pay Element corp for support services. I will look for an alternative.
