If your TV has native Roku on it, this wouldn’t help at all because you have to run Kodi through HDMI input to the TV anyway, right?

Is there some open-source replacement for Roku? All I really use it for is a portal to my streaming services that’s easy to navigate with a remote. I’ve noticed my Roku become increasingly more overrun with ads ever since I started using it 4-5 years ago to my dismay, and it’s obviously not stopping any time soon. I’m vaguely aware of Plex but I have no clue where to start with setting it up or if it would even meet my needs

To be fair, most people I know don’t have the financial flexibility to quit their job if they’re asked by their boss to do something objectionable
