The EU will still want to protect their capabilities to spy on people's phones, now, or maybe in the future. They will not want to mess with that by giving users too much control over their phone.
In the end it is always people making the decision. That is who "they" refers to.
But you are right, the EU should be much more unified and consistent. Also, have their own army that they could send into Ukraine to put Russians back where they belong.
