Is it safe to add family members to Google?

Question

YouTube

I bought a YouTube premium subscription, I would distribute it to several people since there are up to 6 people. What additional access rights will these people get besides viewing YouTube without ads? What information do I disclose? Can someone see who I added?

Answer 1

Your YouTube account = Google account to all Google services including google pay (i.e. purchases through a card linked to your account) on all your mobile devices, synchronization of contacts, backups (i.e. access to archived messages in chats for example) and so on.
If you give someone a password, then this person will be able to use your account on their devices to the maximum.
Some believe that soon accounts in such global services will be very strongly integrated into our lives, which means that if there is any problem (Google will be offended by you, there are a million reasons, including erroneous ones, and the support service there is a 'nightmare on elm street'), then it will affect absolutely all your linked accounts (by the way, multiacc is prohibited, but it is taken into account by Google) on all your devices, including your work.
Are you ready to entrust so much your future life to your relatives?
And in five years? Ten?
