Others have addressed 1. 2 - The dot essentially forces a bar. It's not an overlay on the application's graphics. This is what is shown in the images. So there is something to crop off. Not to mention, if it is known, it can be planned around. This is exactly what television has been doing for years. There are scan lines that don't get shown on screens despite being broadcast. 3 - This is almost as disingenuous as the article. The dot is there to inform the user of the device/screen that they could be recorded. The audience during a performance would qualify as a user in this case. It's basically an indicator saying, "if you can see this, it's possible the device showing this is recording your audio". That is completely relevant for an audience. If you think it's not, then why is it relevant for anyone else. There are thousands of excuses one can use to justify hiding this information from anybody. Once you are potentially violating my privacy, it is relevant to me.
