I wonder if that'll turn out to be true. There's no reason Musk has to let them, and I could see him just blocking links from The Guardian in retaliation.
For the record, I don't support temper tantrums on either side, and it feels like this is a very politely stated temper tantrum. But, I also think everyone should get off Twitter. Maybe what I don't like is just that everybody should have gotten off Twitter many years ago, because it's bad for journalism and the human brain in general, and not suddenly pretend to realize it's a bad place now that it's coincidentally less popular, and there's less incentive to hold your nose and stay. Seems hypocritical.
