Regarding the use of the product name, the Paypal Sucks website is perhaps the best known of this genre. If you Google Paypal the "sucks" site is on page one of the SERPS.

They have been using Paypal's brand name in this way for years and they even use modified versions of their logos. As you know Paypal is a very large company and they have been unable to do anything about it, which would suggest to me that you can tell them to {insert expletive} off!.

IANAL.
