We have XXI century for 21 years so far and we have (in Europe) GDPR for three years. Privacy is key concern for everyone using Internet today, but not in Google.
Because Google hires a complete ignorants and morons at deciding level, which completely doesn't understand the meaning of the word "privacy", you are forced to use your real name in every Google Service.
And hell can get cold, but you won't be able to change this.
Effect? Millions of people are changing their names in their Google Accounts to some fake ones. Congratulate, Google Mornos!
Today, for a very short moment of time, hope has returned. As I have discovered that you can finally provide your nickname instead of your real name:
Unfortunately, it was a very short moment of time, because... Google employees morons who doesn't give a shit about your privacy. And it turned out that...
You cannot display just nickname. Again your full name must be visible to anyone interacting with anything you have ever created within your Google Account.
Well... we're going back to the old school again...
Why? Simple! Because Google hires a complete ignorants and morons...
