You're describing negotiations that happen before significant money and services have been exchanged; this PayPal "negotiation" occurs after. This turns out to be a rather large difference. Indeed, it's the difference between a contract negotiation and a hostage negotiation.
For the better of part a decade, Paypal has published a "Terms of Service" which you are required to agree to before you can use the service. Business users are required to agree to the TOS again. They regularly email customers regarding changes to the terms of service, and these terms of service are always publicly accessible.
If someone chooses not to read the TOS, that's on them and it is their failure as a business operator. If they wanted to renegotiate the standard terms of the TOS, they should have approached Paypal before agreeing to the TOS or before launching their business activities.
It's not a hostage negotiation--there's no requirement that you start using, or continue to use Paypal.
No, Patrick just got finished explaining how people who do pre-order business with Paypal could have reasonably been expected to know what Paypal was going to do.
