Directly through the manufacturer. Most offer trade-in promotions on par with, if not better than, any service provider deal, with the added bonus that you're not locked into a 3 year installment plan with said provider.
It'll still be about whether Epic gets mobile ports or if Valve or another service streamlines and integrates a Proton/Winlator solution. Not the worst bloatware but I'm still holding out for something Steam based. It's mid-December and still waiting for the games EGS they said would start dropping before the end of the year
Serious question though, why? It's not like they offer a ton of apps. It's not a real app store, it's effectively just a launcher for the 3-4 apps they have.
Google is by no means a monopoly. There is iOS, few other systems, and even on android you have a dozen of stores.
And the pre-installed Google apps package deal is completely fine.
You get a system you would have to spend billions on, infrastructure, verified brand, and much more, and you get their product for the price of bundling it with few more, which end user can just not use or even debloat.
You must really hate Google to think this is in an way unfair.
