They’ve been warning everyone for over a year. They’ve been individually messaging affected phones for months. Nobody can really say they didn’t get warning.
This is quite a misleading way of framing the communication. The telcos were clear about 3G phones no longer working many months ago, but it has not been clear at all which 4G phones would be blocked. Communication about this second problem only started recently and even then it was very unclear. Blaming consumers for not throwing out their new phones when they are receiving mixed messages over whether they will continue work is hardly a rational position.
Don’t go to .ml communities if you dont like their moderation. Their users don’t brigade us so I’m not sure why we would need to defederate from one of the largest instances, especially given the issues with lemmy.world.
