Another basic feature that’s missing is sharing a Gemini chat as a link anyone can view.

OpenAI figured this out: it’s awesome marketing when people send each other links to the app with a convenient text box to continue the conversation. It’s viral.

Google meanwhile set this up so that “anyone with the link can view” is actually “anyone with the link and a Google account”.

That’s grade A failure of marketing.

The PM in charge of that decision ought to be walked off a plank.

This doesn't sound right. I just opened a shared link in a fresh incognito window and it works fine.
