I don't disagree with the core point that long-horizon, FOSS communities should think twice before operating atop services like Google Groups. Also the particular quality atrophy and feature degradation sucks.
Perhaps it's better framed to say that Groups is not prioritizing the particular users that the author is speaking on behalf of (ack, the monospace thing is a serious bug beyond FOSS communities). Google Groups and the shared infrastructure underneath is a critical piece of GSuite and GCP in many places, and I'd be very surprised if it ended up on the Killed By Google list.
