First of all, I am a new user. Just one week with Graphene.
I think that I read some articles, and topics about Obtainium, which is considered as a secure and private alternative to Aurora, Play and F-Droid.
In my opinion being Obtainium user is quite risky.
From the beginning of my journey with GOS I was using Aurora Store without Google services and installing only open source apps without Google trackers. The exception was GCam.
Aurora updates are great, I have never problems with them.
I understand that the main problem with installing from Aurora is probability of downloaded malformed application?
Is it not same if you are connecting to wrong source with Obtainium for example?
Assuming that I am downloading proper apk from official source, then checking it integrity with database can I have right to believe that using Aurora as the updater may rescue me from malware apps? If it's true, then I do not want to use Obtainium anymore.
