This was obvious, wasn't it? A country with the largest population in the world has introduced CBDC version of its paper currency, it's obvious that they would have the highest number of users of digital currency, also in a country like China where financial inclusivity is quite high, but obviously, you can't compare Bitcoin and Digital version of Yuan in any way, in fact there is a good chance that people using Digital YUAN would still find it difficult to operate private key bitcoin wallets. But I disagree with your statement that Bitcoin has failed to do so, the best thing about bitcoin is that it didn't imposed it's usage, you are free to choose whether you want to use it or not while the same isn't the case with Yuan which was imposed in the country.
I think the points @coinycoiny is trying to make are clear, and of course important to not place Bitcoin on the same balance as CBDC.
As we all know by now, adoption is all about context. China with the largest population on Earth and its non-democratic ways make it easy to look as if the people are embracing the new digital version of the Yuan, even if this may not be a citizen choice.
Bitcoin (and most crypto) on the other hand has been created to replace finances that are nothing less than centralized and pushed upon people. For sure the reference OP is making is not a fair comparison, and thus one of no meaning. Though, it opens this dialogue which in itself is a good thing as it leads to further education.
