Tangentially, I see a lot of people here upset that apps can react to your screenshot before it is captured. I think it is helpful to think about it as a tradeoff between freedoms:

(a) the freedom to screenshot any content on your own device (b) the freedom to share content with others that cannot be screenshotted

It can be annoying when DRM or privacy features block a screenshot, but I think it can also benefit the platform ecosystem that you participate in as a user too. Idk!
