They might not be lying about Paypal holding on to funds. That's what they do in disputes. They've also recently (last six months, I believe) enacted a reserve system, so they'll hold on to a % of all your Paypal funds, judged based on certain risk factors. Legal, credit score, disputes, and so on.
I do think they're scapegoating to the highest degree here, but there may be a tiny grain of truth in that Paypal are probably hold on to a decent chunk of the payments they've recieved via Paypal.
That statement may be TRUE. Its the rest of the LIES I'm worried about. We're all supposed to believe their word is now gospel when they have lied from the start. The Coindesk article sums up this whole mess pretty well.
