Okay you seem pretty cemented in this belief. My belief is that there are plenty of CMSes available. The plugin ecosystem is a side effect of a poorly developed cms, not really a feature. You can abstract a lot of need for plugins by using a CMS that isn’t “just the basics to support a plugin culture”. If you want to lock yourself into wordpress requirements then you’ll never escape it.
I don't disagree with you that there are alternatives, I'm just saying that this requires a level of knowledge, expertise, and desire that the average WordPress user simply doesn't have. WordPress is so old and so entrenched that it will take a really big push to get them to go anywhere - and the recent debacle isn't that big enough of one.
Wordpress itself doesn’t have to be deprecated or removed. It can be around forever, but people should have agency to use something else for new projects.
