The fact that someone has a public profile as an artist does not make them, or their music, fair game

Indeed it does not, particularly from someone who is a performer (of sorts) himself. Jim Causley, in common with many artists, cares a great deal what is written about him if it is inaccurate. I'm sure he wouldn't mind a cogent analysis of his style - he might indeed welcome it if it enabled him to make beneficial changes. But to state baldly that a sound clip had made you want to throw up is scarcely informative and very hurtful.

As for Jim + Mawkins doing different things, it's not the end of an era but an opportunity for the individual musicians to do, well, different things as they have always done in order to progress. It does not necessarily preclude further Mawkin + 1 gigs in the future.In the meantime, get Dave Delarre's solo EP Blue Beginnings and catch up with Jim Causleys's previous solo offerings.
