Flickr is now independent, but it was part of Yahoo for so long I’d guess most people having all their photos in it probably used a Yahoo account. I’ll confess I tried accessing mine after a years long hiatus and it didn’t work (endless password resets)

On alternatives, which storage/sync and management service do you see working at the same level as Photos ? I’m genuinely curious and would move if it matches up (Basically, what is the Gmail->Fastmail like go to alternative for Photos ?)

Image identification looks to me like a very fringe use for a photo storage service, or perhaps you’re referring to searching all your photos for specific keywords ?

PS: Reminds me of the photos services curse from “The Prompt” podcast, where every time they’d present a competitive photo service, like Everpix, it would go out of business or something horrible happen to it a few months in.
