In my journey to remove myself from as many unethical companies as possible I was hit with one of several hard lessons, that even if I remove my dependency on corps like Google, I may not want to sacrifice services who themselves depend on it. For example, I use Home Assistant. I value several (external) community made integrations and therefore use HACS. Well, HACS is a frontend for all these extras, which are exclusively hosted on Github. So I 'can't' delete my Git account, rather keep it around for API access.

I have some other services like Shopify, who I don't really trust but who are frequently the only adopted sale point for many merchants, who themselves are ethically sound or, subjectively, the 'best' source. Who better to host a throwaway email account for services I reluctantly connect with than Google, aha.

What I'm saying is, I'm finding total deGoogling a challenge, and I wish you the best of luck. At least there's alternatives to the Play Store; Aurora, F-droid, and ApkMirror||ApkPure
