How to play YouTube TV content on Safari and DuckDuckGo browsers?

YouTubeTV will not play content on either Safari or DuckDuckGo - both browsers are current versions. This is a persist problem for several years. I can play YTTV content on the Brave Browser. Is there a workaround? Previous posts have stated that Apple has not implemented the means to decode YTTV’s encryption. If Brave can do it why can’t Apple?
