Enable to all my users by default

Hi, thanks for the kinds words. It is possible to do with the use of (code) a filter hook. You’ll need to create your own plugin, mu-plugin or put it in your theme (which is advised against generally anyway).

Check out the wiki on GitHub for more info: https://github.com/danieltj27/Dark-Mode/wiki/Filter:-not_using_dark_mode

This should do the trick:

function dtj_dark_mode_user_default( $user_id ) {

	// Get the user's Dark Mode preference.
	$user_pref = get_user_meta( $user_id, 'dark_mode', true );

	/**
	 * Does the user not have a value set?
	 * 
	 * If 'false' is returned by 'get_user_meta' then that
	 * means that the user has not saved their preference yet
	 * so set the default value instead. This applies to all users.
	 * 
	 * You can do a further check on the '$user_id' to only limit
	 * this to a certain subset of user's on the website.
	 */
	if ( ! $user_pref ) {

		// This is the default value when no preference is set.
		return true;
	
	}

	return false;

}

add_filter( 'not_using_dark_mode', 'dtj_dark_mode_user_default', 10, 1 );

I’ve not tested this properly, so you might need to pay around with it to get it to do exactly what you’re after.
