provides fewer face-to-face interactions (amplified even more by Covid). The last neighborhood I lived in we hardly knew our neighbors that weren't also LDS (we made up from 10-20% of the neighborhood). It wasn't that people weren't friendly. We just all got home from work, hit the garage door opener, pulled in, hit the garage door closed button and never hung out outside in the front yard. Everybody else was the same. Unless a non-LDS neighbor had a kid in the same grade as one of my kids, I probably didn't even know what they looked like. In decades gone by, people went outside and sat in their front yards in the evening. Others would take a leisurely stroll around the block and stop to talk to neighbors. Not so much anymore.

Another reason, as you suggest, is that others are doing it. When it comes to private details, each new generation seems less concerned with privacy than the prior generation. We're all basically tracked by our cell phones and our internet usage. People that have grown up with it are very comfortable with having less privacy.
