It's not what you thing PIA stands for.

http://www.thinkdigital.gr/web/files/richeditor/filemanager/140204_Samsung_Pia.pdf and other finds that Samsung wants to use the platform for their own end. "PIA is an advertising area located in the Smart Hub, Samsung SmartTV’s home screen that all users have to visit in
order to access SmartTV contents. Ads displayed in PIA will be shown to all Samsung SmartTV users, every time they access Smart Hub.
If the users clicks on the PIA ad, a full screen landing page expands, delivering more information with greater interactivity!"

This seems to spill over into what you are complaining about.

Frankly if the maker does this, does not deliver the experience you want, I give the advice to return the defective, doesn't fit the need of the user device.

Yes, that's right.
