Making things less addictive helps.

I also recall someone once saying that privacy isn’t about maintaining secrecy around one’s inner life, but rather the capacity to regulate or control how one shares it.

Feeling a lack of control over privacy makes lots of people cagey about opening up to others, and that’s a killer for intimacy and trust. Some of the problem is tech that doesn’t respect privacy, but the prevalence of such tech has also changed culture, and so one has to be more cautious with people who have been trained by their tools that privacy isn’t to be respected.
