I found the opposite. Less of a hassle to install ublock origin in Firefox on PC, Mac, and Android that support it, or Brave browser on iOS or the others for a chromium browser.

Rather than keeping a separate device on the network, having to keep it updated, it was also unstable on a rpi when I tried a couple of years ago.

I guess my TV shows YouTube ads, but that's kinda it. Netflix, HBO, Disney+ do not have ads and my LGTV Web OS seems Ad free in the menus without me doing anything.
