Unfortunately, due to a new development in the ongoing legal
proceedings, we are required to suspend this service again until
further notice. We can’t share more details.

Not surprised, and not sure what to make of the “can’t share more details” part. Again, if you want to avoid visiting X but want to see the content posted there linked from other sites (and, let’s admit it at this point, there’s not just a lot posted on X, it’s resurgent in popularity), install a browser extension like Litterbox (Safari) or Post Peek (Chrome).
