Personally, I trust paying a person via Paypal vs. a generic credit card form. Or anything really that doesn't let me trust you with my 16+3 digits that grants full access to drain my credit.
Agree, but reluctantly. Given Paypal's horrendous history of freezing funds and poor customer support, I use it only when I have serious doubts about a site's generic form.
Paypal has great customer support if you are a consumer, it is only sellers that have issues. And usually it is because someone thinks it is a good idea to use Paypal as a donation processor (which it is NOT meant for) and are surprised when they get into trouble.
Agree, I my credit card recently got expired and I had to update it in every single website - github, comcast etc. I just connected PayPal with Github and I will just need to update it in one place now.
