The issue is that the block editor and classic editor have very different audiences. In theory, the former is for the folks who'd use SquareSpace, Wix, etc. Non technical folks who want to customise everything in a 'user friendly' way and have absolute control over their site and its content. Meanwhile the latter appeals more to agencies and large businesses, who have a bunch of users they want to only allow to post specific content/make specific changes, and a vision for what the site should be that they don't really want changed via random blocks and settings. Gutenberg was meant to win over the former group and stop them going to SaaS based solutions, but ended up being a headache for the latter, which were arguably a bigger percentage of the folks using WordPress on a professional basis. Hence the ecosystem getting fractured like this.
