They technically announced it [1], but I agree that it got next to no coverage. Presumably they deliberately "silently" put the announcement on their blog without circulating it to news outlets. HN discussion at the time [2].
Ah, thank you for the links. I searched prior to posting but the title on [2] is very non-descript. I was expecting a lot more outrage considering the size of this hike is pretty massive for merchants that process a lot of smaller transactions.
I have a merchant account with PayPal for my side business. I received an email notifying me of the change. I presume this is legally required for this sort of change to the terms.
