Earlier quoted context omitted.
So there is no user choice, technically just a lesser commission. Nothing stopping Google from upping this 5% "fee" to 10% when they feel like it. This is still a loss for devs, I was hoping we can just rip of Google garbage payment system and use something like Stripe, or whatever new companies that would've emerged to fill our needs. Obviously they'll give a sweet deal to massive companies but not the small devs.
Googler, opinions are my own. What issues do you have with the Google payments system? With the stripe bring that Google does not already have? (Outside the fee issue most people raise)
They offer an awesome development experience and have other complimentary products that all work well together. Especially if your service is multi platform (web, ios, android).
