(About the page design) I don't know what medium is doing. They have bars both along the top and bottom of their page, which cramps reading. Instant reader mode click to resolve that, which shouldn't really be needed on medium.
It's kind of curious that they posted this on Medium instead of some Mastodon site.
Mastodon is a microblogging platform. This does not fit into the format.
It shouldn't be posted on Mastodon itself, but they should just set up a simple static blog somewhere. Medium is the opposite of Mastodon in so many ways (centralized, heavy data-collection, etc.) that it really makes no sense for them to be using it as their official method of making announcements.
