Another way to look at it is the OS makes certain guarantees to the developer around security. Giving control of this to the user would erode that guarantee from the OS to the developer. The result of that is that some developers would simply never display some information (e.g. due to their own contracts or reasonable concerns about fraud/abuse/etc.).

Very similar to the video pipelines in modern devices. Prior to video pipelines which the OS could attest could not be hijacked by the user, many content providers simply would not allow e.g. Netflix to release their content on certain platforms. That the OS does provide such an attestation option for developers allows uses that otherwise would not exist.

This is phone OS developer's fault for even allowing it. When I take a screenshot, I expect to have an image of exactly whatever was displayed on the screen at the time. Its not a picture of your app, its a picture of my screen. Some banking apps used to (or still) prevent this and now some apps get a hook to insert their branding. My device serves some master other than myself.

This exists for a very good reason. It’s so if an app is showing a password or bank account number or other piece of sensitive information it doesn’t accidentally end up in a screenshot. I think there are other places sensitive information won’t show. Bluesky, and apparently others, are abusing the functionality for advertising purposes. I think it’s a good thing it’s there. This functionality should be easy for apps…

But how can I take a screenshot that intentionally shows the password or whatever?

I have 200+ different passwords stored in iCloud Keychain, each 20+ characters long. How am I supposed to remember all of those? Do you use the same password on every site? How do you deal with data breaches?

You can just use your own password manager and it wouldn't automatically do anything to apps on reinstall, right? Or a physical notebook, maybe.

I’d love to have my own password manager that syncs between all my devices without relying on a third party server, but I don’t know of one. Do you?

A physical notebook is so easily lost I wouldn’t even consider it.

Which is why everyone should root the their phone to turn this kind of shit off.

Uh, no? I highly doubt that a non-occluding watermark on screenshots is even in the top 100 gripes most people have with X. And I don't use either platform. If anything your argument is an accusation of bias without any discussion of merits.

Not sure why you think anyone is suggesting that non-occluding watermarks are a gripe people have with X. GP is saying that BS gets a pass where X would not for a user hostile action.

Yeah, the dead comment really cements the bias of hn despite what people claim.

I don’t use either platform, I have no interest in the debate. As an outsider looking in, the bias has been proven.

Not that it matters much, I am left-of-center generally speaking.

Why is this feature bad? As someone who develops apps for confidential conversations, making it harder for people to screenshot the confidential stuff is a feature the sending party wants, that is why they send in your app as opposed to others. It doesn’t make things impossible, just hard enough that 95% of people won’t bother to take a copy. Same for example with disappearing audio messages on whatsapp What I don’t…

It's mostly dumb because of obvious analog loop holes. I at minimum carry 4 devices with cameras, often as many as 12. If I want to capture the disappearing message... I will do it; making it annoying just makes me pissed at the developer + the is.

I use KeepassXC and Syncthing. It's not a single password manager doing both the managing and syncing, but it works very well, and I sync between phone/laptop/desktop without any third parties.
