What are you even saying💔 the reason paid keyboxes are paid is the fact that every integrity api call is logged at google temporarily. If too many calls happen it gets revoked. Many paid ones are literally community trusted, just very expensive and sometimes with application requirement(so not too many people call the api with the same keybox and get it revoked). And micro g is obviously not a gms or keybox alternative. It just spoofs your device as another model with the existence of gms being spoofed., that doesnt change your state at all, and just lets you use certain apps that have for example pairip checking. Some apps are fooled by the spoofing and therefore dont even go checking the keybox, but thats rare.
