GPL has the well-known web services loophole, that effectively makes copy-left protections moot. Without that, Wordpress and other GPL-licensed web CMS/frameworks would never have taken off like they have. As for MySQL, notice how no one builds anything on top of it (like TimescaleDB and others did with PostgreSQL), but just uses MySQL as-is without modifying it, also rendering copy-left moot.
