Taking screenshots of everything is no different than elders printing out emails.
I am quite a data hoarder, but I take so many screenshots that I'll probably never look at again, and it occurred to me that this might be my generation's "printing emails" thing.
Yeah, no. Some text services and websites can/do remove content, so you might not be able to return to something at a later date without saving it locally. Once an email has been received on your end, that's it: you have the email locally (or at least in your email provider); it can no longer be removed by the person that sent it.
If I screenshot an exchange on Bluesky where someone is saying wildly racist shit, they can later block me, delete the top-level comment and all the sub-comments, but I'll still have that digital proof. If someone gets doxxed on Reddit and you screenshot it, you've got that forever, even when Reddit deletes the doxxing five minutes later. (They did that with someone that found out who Administrative Results was, and posted all the links backing up their claims. Also, Admin Results in a shitty person, and that's why he and Garand Thumb/Mike Jones get along so well.)
My mom doesn’t know how to save an image to her phone or iPad, so she will use her camera on the phone to photograph something on her iPad to send to my aunt.
There are web browser addons which can change the export to a png, but if all else fails, imagemagick after saving the image takes less time than screenshotting and cropping.
Maybe that's just a me thing. Other than just stuff to try and remember for later, it's usually pretty dumb. Stuff like: items in some online store, images on a search page generally (not downloading anything specific, just snapping a shot from the general view), etc. It's kinda hard to explain, but let's just say out of a set of 70,000 pictures, at least 50,000 are screenshots.
I take pictures of things I want to find faster over hunting for emails or text messages while on vacation and there's maybe spotty Internet. i also do this for cooking directions.
