Cryptography rearranges power: it configures who can do what, from what.

I'd argue that the reverse is really the issue that needs more attention. Online systems that do not provide strong cryptography rearrange power, as compared to their offline equivalents.

It was not feasible to scan all phone calls for keywords in 1970, since that required effort from humans to do the patching and listening. The power dynamic changed when our industry brought those calls into a centralized, trivially-storable clear-text format. Encrypting the conversations is simply a partial return to the status quo of a few decades ago.
