> Keep in mind that today due to the great popularity of Docker, Alpine Linux is one of the most deployed operating systems currently in use, because within every other operating system that uses docker, the docker image it uses is almost always Alpine Linux.

Isn't this a little overstated? I'm willing to accept it has a majority, especially once you get into custom images, but e.g. docker's library images are usually debian based, with a -slim or -alpine variant available, and of developer provided images on my network, debian + derived images have a majority, while Alpine's statement leads you to expect some kind of 90% share.
