Corporate publishers are probably feeling the burn of the enshittifcation of Medium and then Twitter, and annoyance from the Instagram ad volume and Threads uncertainty. I bet they would welcome an something more boring like a Wordpress blog that was totally under their control. The critical part that's missing is an easy way for end users to subscribe (e.g. a popular/easy RSS/Atom/feed reader standalone product or feature).
I want to be able to have a fediverse feed that's as much RSS feed as news feed, but that's my preference. I'm really glad WP is making it easy for folks to use ActivityPub.
