We just said fuck it and paid the $8 for a month of Peacock. It wasn't worth the hassle of trying to find something for free, sifting through innumerable scams and fakes, for the hope of catching a glimpse of maybe one event with commentary in a foreign language before the stream inevitably goes into terminal buffering.
Now, we can see live coverage of just about every event, in HD, with no ads, plus curated highlights, and they've even got a nice multiview feature where you can keep an eye on 4 different live events at the same time. I'll just cancel once the Olympics are over.
This is one of those times where the price they're asking seems more than reasonable for the quality of content they're providing.
