That's strange, I didn't get anything about UPS changes. Wonder what gives?
Here's a cut and paste of the first paragraph from the ups link I provided above.
iabol for Commerce
Starting May 2013, purchasing and printing UPS labels through PayPal® will no longer be offered. However, UPS shipping services will continue to be available to eBay® sellers when listing items for sale. It looks to me like they are addressing shippers who have actual ups accounts and who printed labels through PayPal.
That covers the first line of the paragraph quoted above.
The second line seems to say that if any individual lists items for sale on eBay that the ability to print labels through paypal will still be available.
When I ship an eBay sale through ups I start at eBay, go with the item just sold and press ship button from there. It automatically takes me to PayPal and pops up the shipping slip for the item.
Looking like this won't impact ebay sellers who do the shipping through eBay/PayPal and NOT their personal ups account. If that's the case, it is good news and there is no reason to go through the hoops on their other offer.
