They have ads on the home screen on their streaming boxes too. Maybe not as bad as their TVs, but definitely bad enough. Roku has getting steadily worse for quite a while, but their products have really gone to shit over the last several years.

For those looking for an alternative solution, one option is to buy a cheap Onn streaming box (which runs Google TV), and then side-load an open source launcher onto it. No more ads, but still a nice user experience.

The only wrinkle is that you'll need to use Adb and hook it into your PC one time and use some terminal commands to get the new launcher to stick around after device restarted. But it's not too bad.
