Competition is always good for a consumer, especially here where right now you simply don't have a choice but to pay the rent to Dolby on every TV audio device.
Luckily I'm not a capitalist and am not convinced my life will be improved by shaving costs down to nothing until there is only one supplier left standing. Fort that matter I'm not much of a consumer, I'm still using a 10 year old TV XD
What's weird to me is how google is selling this as a win for the public, when the marginal costs added by Dolby are so low. Even in the audio production space, Dolby stuff is a little expensive for an individual (surround sound plugins costing hundreds of dollars) but it's not a big overhead for a recording studio. Their product is quality and consistency at industrial prices and imho they deliver on this.
There isn't an underground of frustrated audio engineers dreaming of how theatrical sound could be so much better if it weren't for big D. Spatial audio rebels build quadrophonic sound systems for raves, but you didn't hear it from me.
C'mon, this is market capitalism 101
