This weird grudge match is devolving more and more into schoolyard tactics. I've been wary of all the Automattic service integrations even in self hosted WP, and it's turning out even worse than I could imagine. Not with simple enshittification, but with a complete egomaniacal tantrum.
My earnest hope is that all of the former WordPress community supporters and contributors, swivel and start investing their time and effort into WriteFreely.
I'm afraid there won't be one replacement for WordPress, because it has so many applications. The pure blogging aspect could be substituted by Writefreely, more advanced users may go to Ghost, and I'm not sure what small business and corporate websites will turn to?
