The calculation explained on the page wouldn't rank MariaDB properly. Debian's MySQL is MariaDB but many people are calling it MySQL so it increases the ranking of MySQL. Job offers with MySQL sometimes talk about MariaDB.
Whether that would be enough to rank MariaDB higher, I can't say.
No, that's not correct. MariaDB is a "hard fork" of MySQL, and they've both grown in different directions. MariaDB used to cherry-pick code from MySQL 5.x, but hasn't been "drop in" compatible for quite a long time, especially since MySQL 8.0 which came out 7 years ago.

I always thought of MySQL as the specification and MariaDB as an implementation?

Even just looking at table design and schema management functionality, here's my increasingly-long rundown of subtle differences in features and syntax: https://www.skeema.io/blog/2023/05/10/mysql-vs-mariadb-schem...

I wouldn’t trust the data there very much.
