Google privacy cred is ... excellent? The worst data breach I know of them having was a flaw that allowed access to names and emails of 500k users.
If you consider "privacy" to be 'a giant corporation tracks every bit of possible information about you and everyone else'?
They don't even let you have multiple chats if you disable their "App Activity" or whatever (wtf is with that ass naming? they don't even have a "Privacy" section in their settings the last time I checked)
and when I swap back into the Gemini app on my iPhone after a minute or so the chat disappears. and other weird passive-aggressive take-my-toys-away behavior if you don't bare your body and soul to Googlezebub.
ChatGPT and Grok work so much better without accounts or with high privacy settings.
Link? Are you conflating with "500k Gmail accounts leaked [by a third party]" with Gmail having a breach?
Afaik, Google has had no breaches ever.
