This list is supper useful, but I think it would be even more so if it gives an indication what projects are already backed commercially. I.e. some of the OSS projects are commercially supported, such as all the ones from the QC hardware vendors. I think it would be useful to indicate this.
Certainly any high quality non-commercial QC project may become big enough to attract commercial support, but a project, for instance like Cirq, initiated by Google, will have this support early on.
