Re: I was going to say...
"I won't have MySQL, Virtual Box, Java or any of their rubbish."
VirtualBox is licensed under GPLv2. What is your concern? https://www.virtualbox.org/wiki/Licensing_FAQ
OpenJDK is available under the GPL license. Same question. https://openjdk.java.net/
I prefer MariaDB over MySQL just because Oracle, but MariaDB is also GPL.
