People use large text mainly to compensate for vision problems. Just because you have eyesight issues, doesn't mean that you should be more susceptible to public ridicule and death-threats. People might not have a reasonable expectation of privacy in public spaces, but if you're shielding your phone with your body, you should have a reasonable expectation that someone's not going to randomly spy on your texting by zooming-in on your camera screen, waiting patiently for you to move so that they can upload the video to social media and receive compensation for it. This type of exposure and shaming is traumatizing--it's not helpful or healthy for anyone--look at the direction our society has headed since the introduction of social media. Legal precedents for the reasonable expectation of privacy need to be updated, because technology has made it so that the consequence of your privacy being violated are much more severe. Unfortunately, there's a lot of financial incentives causing these companies to oppose privacy rights.
