When I first got the Roku, I had a "Oh, HELL NO!" moment when I saw that the Youtube app delivered fresh, sticky ads to my eyeballs--for which I have zero tolerance on all my devices.
A little research resulted, and I ordered a Pi 4. A couple of days later, after it was set up, I realized that PiHole (and later, AdGuard Home) would NOT filter out Youtube ads (although they work quite well for OTHER ad-filtering).
Shortly after that, Youtube offered me a free, 3-mo subscription, upon which I bit.
$11.99 felt steep to me, but I begrudgingly complied. At $13.99? That might be a deal-breaker.
