Honestly this move makes me think that the whole project needs to be reconsidered by the community. If OS support needs to be suspended as part of a restructure where two people leave, I would not immediately trust CalyxOS again until they come back with months or maybe a year renewed support.
To be clear, I don’t think this means that their past support was bad, but I would be hesitant to use CalyxOS once it returns. For me they’re in the bucket of neutral and untested until they return. It’s a big deal to drop support for an operating system.
