Apple needs to realize that the EU doesn’t care if they left. They barely pay any taxes in the EU and don’t even create much economic value. Since most Apple jobs in the EU are in retail, businesses administration and tax evasion. They don’t produce shit here.
Meta tried to do the same. The EU response was to ask when they’d leave to plan the going away party. Meta was a lot less confrontational after that.
I think that the EU is fully aware that what makes those extra powerful is network effect. And, once they’re gone, something else pops up in their place. The case of Germans using WhatsApp for example would become inconvenient for them for fifteen whole minutes, then they’d jump into an alternative, and business as usual, without Faecesbook/Merda meddling.
At least in germany, nobody cares. We are using WhatsApp over here most of the time
