In general, I think these types of sticky behaviors only change when there's an application that people gravitate towards with the changing behavior embedded.

One such candidate is cryptocurrency and personal finances. The cryptocurrency wallet will necessarily need to be cryptographically secure, so this at least provides an opening for privacy. Tying it to finances means that there's an immediate application, payment processing, that people might want to use and put up with clunky behavior, at least initially.

All this lacks specificity and finances, cryptocurrency or no, bring their own drawbacks, but it does seem like it's possible to me.

The Internet's attention can be fickle and it's easy to forget that sometimes. IBM used to be a titan before Microsoft supplanted it. Proprietary server operating system, including web servers and databases used to deeply embedded until they were supplanted by FOSS alternatives. Digg, Friendster, Myspace, Yahoo, etc. used to fixtures of the Internet until they weren't.
