From my view, WordPress usage was definitely already in decline, but its status as an entrenched juggernaut kept it relevant. Perhaps bringing attention to everyone that quietly used WordPress means those people will start to look for alternatives?
For devs who make a living off hosting/plugins/themes they might keep an eye on things but why move if the money is still coming in?
For users, I doubt much of them will ever know or care -- unless you're on WP engine.
Wordpress is still the most widely available, cheapest and easiest (for non-tech user) to customise software to make a website with.
What would change that, and make me more likely to abandon Wordpress (taking the money my business spends in that ecosystem with it), is if things start to happen, such as a login checkbox with potential legal implications, that gets in my way of using the thing that Wordpress wants me to use.
Whether or not that sentiment is shared across a larger subset of wordpress users I do not know, but I have a pretty strong spidey sense that this crusade is burning down the countryside it’s supposedly trying to save.
Enshittification comes for everything, eventually.
