It is not enabled by default ... unless you mindlessly click through
screens without reading them.

By that standard,  using LVM2 and erasing every hard drive is the
default too ... (Disk Druid - automatically configure files systems)

Or the package selection, or DHCP, or writing the grub to MBR, etc.  All
these things are for an administrator to decide.

SELinux is usable, if you want to use it ... if you don't want to,
great.  That is why you get to install CentOS for yourself and I don't
install it for you and tell you what you can have :)  

I normally don't use SELinux either ... but that is my choice.

But using SELinux is certainly more secure than not using it.

No, their boxes get cracked mostly because they don't do security
updates.

That is, of course, you choice.
