The "free ad-supported television" offerings are actually pretty decent. It's a first-party software profit-center, so the teams making them have every incentive and capability to give them a halfway decent UX. Then on the flip side no-one actually advertises on them, so instead of ad breaks you get 2 minutes of relaxing music and nature montages every 15-ish minutes. Honestly preferable to Netflix's "go-go-go, don't-miss a beat, quick -- next episode is starting!" style.

(My experience is with Vizio's WatchFree+, but the shows are syndicated so I don't think there's much difference from one offering to the next)
