It’s obvious (maybe not) from the text. Companies that are bringing the tools and services to the public. Those companies are risky to invest in, but “investing in protocols” is risk free because there is no way of measuring success beyond a technical spec evaluation in a lab.
Running away from problems doesn’t solve problems. Hiding out in internet ghettos is cowardice not revolutionary.

IGNORANCE.
