The twitter thread mostly uses the full term "cryptocurrency", which is not ambigous. Using the term "crypto" to refer to cryptocurrency is amigous and misleading.

To whom? “Crypto” is the colloquial shorthand for “cryptocurrency”. And I believe those thinking otherwise are reacting to the new usage encroaching on the old. Petty hill to die on…
The "crypto" world, as in Cryptography has far more practitioners and far more hardware and software than cryptocurrency. And most of of the world's communications (among other things) rely on "crypto" as in Cryptography. The "old" usage (as you put it) remains orders of magnitude more instrumental to all of our lives than blockchain technologies (which is a far more accurate name). And will remain so, for the rest of all of our lives.
