I was looking though :
Learning MySQL and MariaDB
[ Russell J.T. Dyer / O’Reilly / 2015 ]
where I came across a licensing Issue.
It says [ Preface Section ] :
"The software license, though, is now held by the MariaDB Foundation so
that it cannot be bought by Oracle or any other corporation."
That is related to the earlier Statement :
"Displeased that Oracle took control of MySQL software, Monty started a new company
(Monty Program Ab) that has developed a fork of the software called MariaDB."
I am not sure what changes are there between earlier & now.
If Oracle could buy Sun which bought MySQL (the Company) earlier , Oracle can still buy MariaDB (the foundation ) now.
How can the license being held by the foundation forbid Oracle from buying the Whole Entity ?
