I am not asking for a replacement to Google Drive, since that's clear, I'm asking for a replacement to Google Photos, which means I'm referring to the functionality that makes Google Photos a separate product to Google Drive (aka, the fancy AI features, automatic image compression, automatic sorting, albums, search, etc).

I don't know if it goes against Proton's philosophy, that's kind of besides the point. I'm just saying that for me to move from Google's suite, as I would like to, this would be a blocker for me with Proton. It's fine if Proton doesn't want to address that market, it just means I personally would find it difficult to make the switch (and likely wouldn't) even though I like a lot of what Proton is doing.
