No, Google is also trying to stop hobbyists running custom builds from accessing services built on their software (the aforementioned SafetyNet). Hackers keep finding ways around this, but Google keeps trying to lock them out.

That’s a side effect. If Google really wanted to interfere with hobbyists, they would mandate hardware-based attestation and all the current workarounds would be broken. It would be much harder to create workarounds for that.
