Why is it recommended to avoid decoupling the copy protection system from the main program logic in PHP development?

Decoupling the copy protection system from the main program logic in PHP development is not recommended because it can lead to security vulnerabilities. By integrating the copy protection system directly into the main program logic, you can ensure that the protection mechanisms are consistently applied and cannot be easily bypassed or tampered with. 

<?php

class MainProgram {
    private $copyProtection;

    public function __construct(CopyProtection $copyProtection) {
        $this->copyProtection = $copyProtection;
    }

    public function run() {
        if ($this->copyProtection->isCopyValid()) {
            // Main program logic here
        } else {
            echo "Unauthorized copy detected. Exiting...";
            exit;
        }
    }
}

interface CopyProtection {
    public function isCopyValid(): bool;
}

class SimpleCopyProtection implements CopyProtection {
    public function isCopyValid(): bool {
        // Check copy validity logic here
    }
}

$copyProtection = new SimpleCopyProtection();
$mainProgram = new MainProgram($copyProtection);
$mainProgram->run();

?>
