I just looked it up on ebay and found quite a few sellers that had touchpad replacements so I’m not sure what you’re talking about…

There are tons and tons of websites where you can create an account with just your email. I wouldn’t expect a third party account to be mandatory. Specially from a product like this one.

Maybe this is a pet peeve but it’s a vpn tool that forces you to log in with an “identity provider”. Yeah, no thanks.
