I don't mind using electronic signatures if a site implements them, for example, using text that says "By clicking below, you are electronically signing blah, blah, blah". I've used financial sites like that.
But I will never use DocuSign, because they create a fake signature for me and then I certify that this fake signature is my legal signature. And yes, they have the option to use your mouse to make a signature. But my point is, they store this signature and then can use it anywhere to sign anything. Nope, ain't gonna happen.
In fact, I was buying a car through Carvana (another horrible company, I found out!), and told them at the beginning I would not use DocuSign, which Carvana normally uses. Their rep on the phone said, "It's fine, you can sign paper". So they transfer this car from somewhere out west to within 1 mile of here, then call me and say "Oh, you haven't electronically signed the legal documents yet, and we need that before final delivery of the car." They were scheduled to deliver the car 5 minutes ago. I told the rep that I was assured I didn't have to use DocuSign and they said, "No, you have to." I told the rep I wouldn't and they could keep their car. Which they did. Then they wouldn't remove my information from their computer systems - social securty number, image of driver's licence, etc. - even though I didn't even do a transaction with them! They would only do that if I lived in CA because it's a law there. I hate Carvana and DocuSign.
