So i say always maintain separate google accounts for individual apps, for individual usages. Separate your personal google account from your business account, from your ad-network account etc. And i would argue that each individual app should own their own account (you pay for this of course, because of the fee per account i guess).
Now the different accounts would still be linked to the same entity, and as stories like this make the news, more people would split their services on multiple account. As a response, it doesn't look like a stretch to me if next time Google would go after all account owned by the entity the deem responsible.
I mean, they already crossed the line of banning all services associated with an account. Wouldn't be surprising if they cross a few more lines as long as there is no critical impact for them.
And blood-black nothingness began to spin... A system of cells interlinked within cells interlinked within cells interlinked within one stem... And dreadfully distinct against the dark, a tall white fountain played.
