Doesn’t Twitter directly suppress such links? I remember there was a crackdown on people linking their mastodon accounts a while back.
And external links in general get a huge suppression in the algorithm because Twitter does not want to recommend tweets that take you off the site.
The platform actively fights you if you want to move elsewhere (which should really be a telltale sign for you to move), so I get why some orgs struggle with that decision. Doubly so if your job relies on the platform’s outreach.
Just to add on to this, in those unfortunate cases where there really is only Fandom, you can use an extension like LibRedirect which will redirect any Fandom pages to a breezewiki instance, which is a stripped down, privacy respecting, no BS front end for Fandom.
