In one case I offered to (and actually did) convert the Word docs they sent me to the appropriate Hugo markdown with front matter and push it for them (not a huge effort, maybe 10 mins per post, I was happy to do it). It worked for a bit but they still ended up pushing for a Wordpress site.
So yeah, it's not down to technical experience required for the edit process.

Because they don't want to call you every time the need to fix a spelling mistake, or adjust fonts or colors or layout, or add/remove a section. What if you're busy or on vacation?
It may also be your personality - do you think you may come off as inflexible and arrogant to your colleagues?
