Definitely pedantic. That's like saying the most popular gas is oxygen. Don't confuse popularity with ubiquity. Phone and browser installs don't count toward the popularity figure, because the users don't pick the DB that gets used there. The only time that choice counts is when the developers decide which DB system to use. From a developer choice perspective, MySQL probably wins out more than any other open-source relational DB. It may just so happen that software relying on SQLite makes it to the most consumer devices and software, but that doesn't mean SQLite is more popular than MySQL.
