Well that's unfortunate. I can take any camera and point it at a screen to capture its contents. Any expectation of privacy on that front is artificial and naive

There is a difference between trivially bypassing protections and having to go though some effort to bypass it.

How many people are going to bust out another camera to take a picture vs. hitting two buttons to take a screenshot?

There's a difference in scale.

I'm betting the number of people doing it will increase at the same rate as the number of apps blocking screenshots. Also would have a relationship to the expectation of security. If more people believe it's secure then the amount of sensitive content will increase

Wanting to get around artificial barriers seems pretty engrained into human nature

How can you say you're a champion of the free web in the same breath as lamenting not being able to wrest away users control over their own devices?!

We can have a free web or we can have a web that replaces app stores completely. We can't have both.

I personally prefer a completely free & open web, but I understand that means I'm going to be installing binaries for some things. I'd much rather have to download netflix.exe than have the current state of browser drm for example.

You'd rather have a locked down connection because you want to control what users do with the content you're selling.

You must have somehow missed the end of their comment that more or less sums up the nuance. ;P

The nuance is basically to drop the “free” - it’s cleaner. Otherwise their business model of sending nudes to random strangers on the internet does not work

Native and web apps shouldn't be able to block (or detect) screenshots. It's MY device. I should be able to screenshot whatever I want.

And you want to disable right click download? Then simply do not upload those images. You do not have the right to take that control away from me as a user.

Why "champion the web" if your whole goal is to take control of users' devices away from them and destroy their freedom in some of the most basic ways?

It’s your device, you can download a program that blocks screenshots if you like.

Considering you can just, ya know, take a picture of it, this doesn't seem important at all.

That was my first thought too. My next thoughts were:

- it protects the platform, to some extent, by reducing the number of unwanted screenshots

- it sets a social norm that taking screenshots is unwanted and makes the screenshot taker look extra creepy if they share the image with anyone

- if a platform provides screenshot blocking, and users (who have all seen pictures of one screen taken from another device) value that protection and make decisions about what to post based on it, the company should think long and hard before deploying a version that breaks that assumption

I think it just leads to a false sense of security for most "normie" users. E.g. Snapchat, people think it must give a screenshot notification or whatever, so it is "safe" for nudes.

Well it is quite trivial to save the photos, either by network interception or patching the app etc. , which ordinary users may not even consider.

Not quite related, but I think "deleting messages" falls into a similar problem. It makes end users think they are "safe" or whatever, but the reality is that if a message was delivered to the other parties phone, they could easily have the original text despite any deletions, e.g. a cached notification or similar.

I wonder about this, versus culturally giving users permission to send nudes, even though they know there's always the possibility they'll be saved.

This is basically it. Yes, there are a million ways around the best protection (even on mobile!) but it's all about user trust and setting norms.

Sorry but I'm glad you aren't able to implement those features on the web.

Right. I'm frustrated when my software works against me.

You aren’t really able to implement them in real life anyway - just like any other form of DRM. If the device can show/play it you can capture it.

> Apple doesn't always like it, but you can plead your case to the reviewers

Since when? What app does this? SnapChat just notifies the counterparty of screenshots, which is largely "nudes", but no other app I've used actually manages to block my screenshots.

ScreenShieldKit is the gold standard for iOS screenshot blocking. They have a messaging app called Confide that includes the feature.

(It's not the app I worked on but it's out there as an example)

Blocking screenshots is a solution in search of a problem. How do you plan to block another phone or high definition camera taking a picture?

Hard mode: capturing straight from the internal display interface

I can just take a photo with another phone, you know that right? It wont be hd but will be enough to compromise privacy if that’s really your concern

You can, but most people's phone is their only phone and their only camera.

Tech people aren't the primary audience for those applications.

they compensate for their lack of tech skills with determination =)
