I had this exact reaction to the graphs that also showed:
1. Movement from Postgres to MySQL
2. Movement from Mariadb to MySQL (and NOT the other way around?!?)
3. Movement from PHP to Java (I remember the sort of people leaving Java for PHP 10 years ago, and I don't think they'd go back, or that PHP people would pick Java as their choice to move to)
MySQL is actually seeing a resurgence as people realize that ACID is valuable and performance is just fine for 99.9% of use-cases.
And Java is seeing a bit of a resurgence as well as people get fed up with shitty PHP and other dynamically typed languages. Java has some frameworks like Dropwizard and Spring Boot that make it not as terrible anymore.

That wouldn't explain why people jump from the database with better ACID (Postgres) to the one with generally worse ACID (MySQL). Or why people would move from the open source non-Oracle fork (MariaDB) to the Oracle-acquired original project that everyone forked away from (MySQL).
> And Java...
Oh, I agree. Java is awesome these days. I'm just making a disparaging blanket generalization about the people who jumped to shitty PHP to begin with.

I think maybe he has the axes labeled wrong?
