Most likely you can’t browse your photos online anymore, unless they add some kind of method to export keys from the device(s). I speculate that it is possible to lose all of your data if you lose all of your devices. There might be option to create local backup from device keys, so it would not be the dead end.

Given the lack of an explicit announcement this seems very unlikely.

I don’t think Apple are stupid, it would have been a clear PR win if they said “we’re adding E2EE”.

Given no explicit statement, and how drastically it changes the nature of their service, I don’t think your speculation is justified.

The problem is, that this was not supposed to be released properly yet. Missleading leak caused them to hurry. About E2EE it is not speculation because it is literally on their papers what I linked?
