Personally I would just love Apple to be forced by governments to open up their hardware by releasing complete documentation of their hardware and allowing to install another os or dual boot. iPhones hardware is really good and would love booting Linux on theses. And then force every services company to provide an API to their services so we have an alternative to their app. I guess Motorola partnering with GrapheneOS will not change anything in this space because contactless payments and some apps will not work and fundamentally because the sales will be way below mainstream brands like Apple/Samsung. Governments need to step up here.
There is only one government that might be inclined to do that and thats the EU. But good luck lobbying this.
