I have one of those Google streaming devices but I hate giving up my privacy. Also, I saw fast food ads on the device's home screen one day and I couldn't disable those. That was the last straw.
So now I use a raspberry pi 5 running arch with Firefox to stream everything to my TV. I even got a remote working with it that works fairly well, moves the mouse and everything. It was a lot of work but now I own my experience and don't have to give Google my data in that particular way anymore.
