Google has a lot of overpaid managers who need to do something to justify high salaries. So I imagine they sit down and then stare at Gmail, a great product that we all like, and then decide to make a lot of unnecessary changes that will make us stop using it. About a year ago I registered a domain to use for e-mail. Even though I currently use Google Suite because I like current (classic) Gmail version, if they really persist and discontinue classic version I will switch to another e-mail service.
