Once again, this only works if you have installed (malicious) software from your ISP on your computer. Otherwise, your browser will detect the interception and show a certificate error.
However, if your ISP is doing that, then *all* websites will show a certificate error, and will be inaccessible. To fix that without compromising your security, you must switch to a different ISP that actually respects your security, remove the intercepting device, or, yeah, use a VPN.
