Yes, but that's only a minority (very vocal, though). Most people in the Deaf community accepts people who have CIs because the times are changing due to the emergence of technology. Today, a high percentage of babies get CIs and for many of them, it is successful and they are able to function "normally" without learning ASL.
It wasn't always the case because CIs is a new technology and it became common only 20 years ago. At the time, it wasn't very effective. But we've gone a long way since then.
