Cloudflare is still software. We consume these services by writing code after all.

Another example would be postgres. I can rent postgres, including whatever hardware is used to power it, from AWS, GCP or Azure. Or anybody really, like DigitalOcean or Heroku.

My 'postgres' code will run on every vendors service. The same applies to containers.

That is how I understood the comment 'Linux and HTML', something that is standard and universal, that affords portability and let's vendors compete on quality rather than relying on vendor lockin.
