@DeletedUser127 Aurora store enables (but does not require) download of Apps from servers owned by Google, without meeting Google's requirements (in their terms of use) that each user do that using their own registered account. Enabling users to bypass Google's TOS is virtually an invitation for Google, if they choose to, to counter.
GOS doesn't do that. Google voluntarily makes an open source version of their source code available, and - consistent with that open source model - GOS developers add features to that, and report fixes upstream to Google for consideration. The system they distribute does not download anything from Google-owned servers. When users do seek to download apps from Google-owned servers, the default recommendation is to use (sandboxed) Play Store and provide a registered username and password i.e. to comply with Google's TOS. Google might not like the fact that GOS is not distributed with Google Play installed and - when users install it - install into a sandbox rather than as a privileged app, but nothing prevents GOS from doing that.
There are some things that cannot be done in GOS because Google chooses not to support them (such as use of Google Pay). But the GOS developers don't try to spoof or enable users to use those things - they acknowledge it as a limitation that users need to be aware of.
