Owners can complain all they want on this forum, but potential buyers don't come here until after the purchase when they are looking for help with the problems.
Potential buyers go to Amazon and YouTube and look for product reviews by those of us who are already owners.
The Amazon reviews in your link are excellent. They definitely show that users are very upset about the advertisements.
Hopefully Sling will realize that the money they are making on the advertisements isn't going to be much if no one is buying their products anymore.
Hopefully we will also start seeing reviews on YouTube that will be showing how difficult it is to watch TV with these adds.
