Why is the website protected?

These restrictions are maintained to prevent user confusion and phishing attempts. If the website design were dedicated to the public domain, malicious actors could easily launch convincing duplicate sites to distribute modified or insecure versions of the browser.

While the browser itself remains completely free and unrestricted, protecting the website helps ensure users can reliably identify official QTech releases.
