Sure, MFT is not dead in general but for his combo of street video and wild live video Panasonic lost against Canon (and Olympus quit and OM System pretending to be in camera business). I must agree. He is right.
There are still niches left for MFT to survive, just not in his life. In my life LUMIX MFT is still the best for macro in combination with the OMSy90 - Canon does not have such offer e.g. for fast handheld macro exploiting video focus stacking.
