Users install plugins which disable update reminders.
Look at the counter of plugins downloads.
I know that some users change the WordPress core files or plugin or theme files, but there is WordPress hooks and child themes.
If user will disable the updates:
- user will not see new features of newer WP versions or plugins or themes;
- user will use software without bug fixes and probably with security issues
So why users disable the WordPress update? Is there any other reasons disabling updates except of modifying the files?
