I have faith that the foundation manages its finance properly. I believe the Matrix protocol (and ecosystem) is full of good, needed, ideas.
But the software produced by the foundation is simply bad. From the clients to the servers. In every single matrix threads, complaints about the UX or performance abound. Usually followed by people from the foundation saying it's fixed in X or 2.0. Or by fanboys saying it's not a real problem and wasting resources on UX is dumb.
That's been going on for almost a decade now. That's a clear demonstration of a lack of ability to execute on a good idea.
