Reminds me of the novel The Light of Other Days by Stephen Baxter: https://en.wikipedia.org/wiki/The_Light_of_Other_Days

I don't generally like his style, but this novel really captivated me. Without spoiling the plot (much), the end-result of everyone being able to spy on anyone anywhere at any time is a kind of societal disinhibition, especially related to sex, nudity, or similar taboos.
