First thing: Privacy. I am aware that iOS is not entirely private too, but I trust Apple Photos much more than Google Photos. You can even enable end-to-end encryption iirc.
Second point is control over my data. I can easily export my photos from Apple Photos as files, whereas Google maliciously separates Photos and Metadata upon export. In my experience this is the same for a lot of other services as well. Being able to easily export my data enables me to escape the walled garden more easily should I get fed up with one system. I also try to use as many open source services as possible for this as well as other reasons.
Apple has a lot of malicious practices too, especially when it comes to EU citizens and third-party app stores, etc. - but in my experience Google is no better.
Lastly, I considered switching to an Android with Graphene OS (privacy focused Android derivate) a couple of times, but the added control over your data comes with a lot of other inconveniences. So for now, I’m just sticking to iOS.
Not entirely disagreeing with you but, what exactly is "malicious" about separating photo and metadata? It could be just how their servers process and stores those photos, with the added benefit of geotagging videos.
I use Google Photos and upload in original quality. When I download from takeout, the metadata is still in the original files. Iirc, only if you select upload in "high quality" where they compress it again, do you lose the metadata in the file stored in the cloud.
When you re-import the images into another program/library, they will not be displayed in the correct order and all other information will be lost as well.
Metadata in general is very useful and contains a lot of valuable information like location data, lens, focal length and device information which you have to manually re-integrate into each and every photo.
I mean yes, I could write a quick and dirty Python script for this, but why should I have to do this in the first place?
In my subjective opinion this is malicious as in it only being this way to make it as hard as possible to migrate away. I highly doubt this is the way their servers store the images as it is very inefficient and the images are likely stored in a database instead. This means in order to retrieve a file they have to process each image anyway, so why not follow the universally accepted and well defined standard and include the metadata in each file?
Sure, but if you care about privacy at all, then surely you wouldn't use either of them anyway? You'd use Ente Photos (available for both OS), or Immich (available for both OS), or any other private solution? So this shouldn't really be a factor in choosing between Android and iOS. Same with the export point. Both have good options for photo backup, and neither Apple Photos nor Google Photos are one of them.
I dislike this logic. It's really a black and white / all or nothing approach. Also, I think the photos app is just a microcosm of a bigger consideration. That being which OS do I trust more overall if I trust some of the built I apps more?
Agree, you should look at the overall picture, not make a decision based on an individual app (which, in case of Google Photos, isn't even built in unless you buy a Pixel or something, it's just some app that happens to be available, for both iOS and Android).
Pretty sure on iOS any other gallery app is just a frontend to the photo stock app. Beside, you can encrypt the whole thing on iCloud so it’s safe (which is what I do)
Yeah, all gallery apps show the same on-device photos, the difference is where they backup/upload them, which is the part important to privacy.
Apple iCloud having the E2E encryption feature is definitely an advantage over Google Photos. All I'm saying is that neither really have much to do with the OS. Google Photos isn't even a preinstalled app on most Android phones, just one of many options you could install, same as on iOS.
Except google photos will nag you every few days to enable cloud sync if it's disabled when you open the app and uses dark patterns to nudge towards accepting. I doubt iOS does that.
