Well less bandwidth and storage is also good for users.

Less bandwidth. Some users pay for bandwidth. Or have a monthly cap. So less bandwidth is a monetary advantage for users. It also may decrease time to play.

Similar, but less ctitical, for storage.

One rule of thumb when switching codecs is "don't decrease quality". I buy that Meta did that. Which would result in a slight improvement in quality (of course sold as big snd noticable) while getting storage and bandwidth down (or allow for better quality in the bandwidth adaptive case).

That saud. Yes. OPUS! Although other aites got quite some bad press for low bitrate opus.
