Not sure why he hates Wordpress, which should do everything he wants, unless he thinks its another big web app. It runs 30+% of all sites. Sometimes popular things are popular for good reasons.
I am perfectly satisfied with markdown as I otherwise do not trust people to get accessibility correct.
it really isnt. its just that people love to throw kitchen sinks on top of kitchen sinks.
I am a SWE, and I also resent the SSG cult. To me it is evidence that SWEs are very, very selfish and user hostile, and take pleasure in gatekeeping anything they can, but then cry when MBAs come and eat their lunch with something better that will surely get enshitified. My mother can't use SSG, she can't write Markdown (and I will not burden her with the need to learn it). Let her login, drag and drop, write WYSIWYG English and hit publish.
