I moderately frequently wonder what is next for me after WordPress. The drama has nothing to do with it though. I don't use WP Engine (have long thought they seemed off), and I don't see the drama causing wordpress.org or wordpress.com to fall.
Likewise. The vast majority of what I've seen so far on this debacle amounts to mob mentality. A lot of people are adding their commentary about Mullenweg, but it strikes me as very surface level and unthoughtful: just saying something to say something because they know what WordPress is.
I don't think the drama will kill Automattic or any of the other involved orgs either. The post-WordPress thing for me, I think, is going to be something that successfully ejects the Gutenberg editor and builds around it. Probably something that borrows from what Drupal has done with Gutenberg and what Corcel has done with WordPress models.
