So maybe open source, [mostly] closed ecosystem? Add a bunch of Spyware from Google and get every app maker to add a dependency to Google services and they are golden for the collection of data on all your "smart" things

Sorry/not sorry for the cynicism; I feel it is warranted given what "open source" means on Android. Google talking like they have noble open source ambitions means nothing. They have a lot of amends to make before they begin to seem like a win for society and the industry and they seem to be going in the opposite direction.
