Actually, there two big reasons why people disliked CDs in the early days.
First, the analog-to-digital converters (ADC) of the time were absolutely terrible. Which resulted in CDs being actually worse than their vinyl counterpart.
Then there was also the people that liked the "warmth" of the vinyl, which is something real that can be measured (at least for old vinyls, don't know for the modern ones). Funny enough, this was due to the vinyl being less 'precise' than the CD, but it had a sound signature that many people preferred, and still prefer today (most modern headphones and speakers aren't neutral-sounding by choice).
