Exactly.

Being too focused on "Google bad" means you're not seeing the bigger picture. microG is only a thing to provide app compatibility for apps that rely on Google Play Services. Which apps do you think do that? Apps with Google libraries that often have fallback implementations and can operate without Google Play Services.

So, given those facts, if someone has microG installed, Google still effectively has the same access as a device with Sandboxed Google Play, except microG users are stuck with worse app compatibility and because of signature spoofing it's less secure and code runs in that privileged context.

GrapheneOS focuses on privacy, security, and app compatibility. microG fails at security and app compatibility. Also, there are apparently leaks (that I admit I don't know the details of) regarding location that make it worse for privacy too. There could be more leaks that I don't know about.

The apps that use Google analytics/ads don't need Google Services on the device. The libraries are embedded into the app, and have just as much fingerprinting capabilities as sandboxes Google services.

microG still heavily uses closed source Google services and even downloads executables run with the full privileges of microG. It downloads and runs droidguard with the privileges it has, giving that full access to the privileged access granted to microG.

Each app using Google Play still has the closed source Google Play SDK and libraries built into it in practice. It's extraordinarily rare to replace those libraries with the incomplete and buggy reimplementations from microG. Very close to zero otherwise open source apps are using those. The closed source Google Play SDK and libraries are therefore still part of the loop and have access to what the app can access. Many of the code paths in the Google libraries directly use Google services without requiring Play services including the full versions of the Ads and Analytics libraries.

The vast majority of data obtained by Play services is via the OS integration and permissions. Apps using it for push messaging, logging into accounts and many other features will send the same data to Google services regardless of whether you use it via sandboxed Google Play or microG.

GrapheneOS stubs out and reimplements APIs on the client side. That includes providing a complete implementation of the Google Play services location API not using on Google Play. These features are being expanded over time. They'll also be made available without having Google Play.

The GrapheneOS approach avoids giving an additional global service access to sensitive data from the OS and apps. microG has repeatedly had vulnerabilities leaking sensitive data to apps including location data. The approach of having an extra service sitting between apps and the OS which handles sensitive data means having to add all the same privacy and security checks as Play services which microG doesn't do in practice and it has caused severe privacy leaks. The main location leakage was eventually fixed but it persisted for years and there are still holes in the location service causing privacy issues.

Unlike microG, sandboxed Google Play doesn't get privileged access. That includes the executables (droidguard) downloaded by microG not getting privileged access. GrapheneOS also doesn't give privileged access to other apps such as Android Auto when those are installed as all the main operating systems using microG are doing. That privileged access gives access to highly sensitive data and doesn't require apps explicitly sending data to Google services, which will nearly all still go to Google services with a partial replacement of the middleware on the device.

MicroG is a sloppy and ineffective reimplementation of google services that does not meet GrapheneOSs privacy, security, and usability requirements. MicroG does not make you degoogled and is not a compromise between being degoogled and making apps work. GrapheneOS, with or without google services, has far better app compatibility.

If you need a functional smartphone that runs the apps you need while reducing exposure to google, GrapheneOS is the best option for that by far.

That's very false. GrapheneOS is a better choice for deGoogling than alternatives.

Sandboxed Google Play isn't installed by default, so our users don't have to use it if they don't want to.

Sandboxed Google Play doesn't have privileged permissions and has no more permissions than other user-installed apps. This means that they have the same restrictions as other user-installed apps.
