You can have third-party Android app stores. Can you say the same about Apple? While I agree that Google has market-dominance, they are not anti-competition or anti-consumer in the same sense as Apple. Android is open source, Chrome OS is open source, etc. Google is actually providing and contributing something back to the community. Apple intentionally locks people to specific hardware and to their app store.
You can buy an Android Phone, and install whatever app store you want.
