Most of us just running homeservers are just random people who have no power over this situation and not enough money to make a dent in their budget needs. For us, Matrix was sold as an open E2EE chat system, and we bought in. Does us buying in do anything for Matrix Foundation/Element? I dunno. Maybe it helps sell Matrix to get broader adoption. Either way, we took a gamble on it, potentially instead of other solutions.

Now the free and open source Matrix homeserver has to compete with a closed source commercial one. I sort of hope there's a happy ending on this one, but it sure looks dicey to me right now.
