Yes, but those folks will quickly jump ship to other RDBMS. I suspect most will simply go with SQLite.

I don't know of anything that embeds a relational database that has the requirements of a MySQL.

Do you think he'd hate them jumping ship to SQLite?

Supposing he actually is being Machiavellian, he wants MySQL not to be so strong a competitor for the middle and high end of commercial installations. He can afford to concede the very low end - Oracle doesn't play there, except perhaps with BDB (a minor sideline).

Surely Adobe Acrobat Professional absolutely depends on the power provided to it by the mysqld process it launches!
