You'll find better answers than I can give based on searching here and searching "Degoogle". I've just rapidly said goodbye out of frustration and am using suboptimal stuff while I work it out.

Re: Google Photos, I actually would have paid Google for extra photo storage as their app is, of course, good. I would have paid out of convenience. But they started demanding I send them my passport and utility bills before I could do that. I understand they likely have their policies and reasons, but can you believe that? I have to send them my passport and data just for the honour of paying them? Straw that broke the camels back.

I already have a Prime account so I just let Amazon scoop up my photos until I find a better alternative. It's actually not bad (has "group by face" and stuff, but not as clean as Google - but maybe I've not delved into it enough). To me, same big tech nonsense, but at least Amazon actually support the customer (support is good vs non-existent at Google) and they let me pay them without requiring my dental records.
