A Subscription does not offer me any real benefit. I do not make rapid changes to my environment.
If I need to keep up with OS levels/or the Main Calibre, I will make the update choice then, not automatic allow my wallet to be tapped.
I find the incessant app (various) updates on Android very annoying
. I think some of the reasons given are just PR spin to update the AD revenue generation
for that AP.
I don't know the details of the CC transfer, but I am not sure change to 'subscription' was considered.
