The CAP theorem illustration provided in article is incorrect and misleading. Actually there is no strict "pick two" limitation. Instead there is some balance between all three properties in each particular setup. For example, Cassandra is shown on "AP" side while it can be put on any side by changing replication factor and consistency level configuration parameters.

Although there is cap theorem limitation, dbs can be configured to satisfy all three to a certain extent.
Example Cassandra can be configured to satisfy consistency also, like, wait until I get the same result from 3 nodes.

In order to sum it up, it supports all 3 but favours availability over consistency which is what i tried to convey through the article. Thank you for asking and making it more clear to the others☺️
