I didn't follow the case with Meta, but isn't it different ? Because you talk about both the GDPR and DMA, which are different regulations.
I agree that a lot of websites (mostly news websites) have the "ad tracking or subscription" model, and I'm not sure if there has been a clear ruling in it yet, but maybe the DMA makes this stricter for Meta since it is a Gatekeeper
Meta offered Pay-or-consent model (nov 23) at 10 euros or so to placate the then GDPR regulators, as the court found contractual necessity as an invalid argument. CJEU stance seems like its valid for meta and they had a long opinion on that.
But DMA regulators dont agree calling it a false choice and asking meta to monetize by non personalized ads. The thing as you mentioned is how other publishers have the same model, which was never objected by any authority under GDPR either (so they clearly seem to think the model is valid). Its obviously a sticky situation where rules are different for different companies in the same jurisdiction when they are offering the same thing.
A counter could be whether if Meta isn't allowed, would no one else be allowed, but you already know the answer to that question.
