I had a wordpress free site for years. Then after I ignored suggestions I paid to upgrade it, I found wp advertising my site address for sale.
Some dodgy company took another author's site, kept her books up but added a load of stuff she wouldn't support to the front page.
The main problem with WordPress is an infantile type named Matt.
1. WordPress has a visual page editor now which has pros (you can create really nice pages without having to "do" code) and cons (it's technically complex, is JavaScript-heavy and can occasionally break)
2. In the WordPress ecosystem there has been uproar when Automattic (Matt Mullenweg's company) used his founder- / owner-powers to go to war with WP Engine about money.
@pthane TLDR is that one of the original authors of #Wordpress, who himself owns one of the big Wordpress hosting sites, tried to strong arm other wordpress hosting sites into paying him money. The noise has died down, so I imagine he failed.
As a software snob I consider Wordpress poorly engineered and ludicrously over-complex for running a blog; from a technical point of view there are hundreds of better solutions. But it is well known and user friendly.
