The feeling of discomfort or sadness when something you have loved for a long time, which was once under the radar, becomes popular and mainstream can be attributed to several psychological factors:
Loss of uniqueness: When something you cherished was relatively unknown or enjoyed by a niche group, it provided a sense of uniqueness and individuality. As it becomes popular and mainstream, it may lose that special quality that made it feel like a hidden gem, leading to a feeling of loss or dilution of its original appeal.
Sense of ownership: Humans tend to form emotional attachments to the things they love, almost as if they "own" a part of it. As it gains popularity, it might be perceived as being taken away from its original fans, leading to feelings of possessiveness and discomfort.
Changes in the fan community: With increased popularity, the fan community around the particular interest may expand and change. This could lead to shifts in the culture, norms, and interactions within the community, which may not align with the initial tight-knit and like-minded group dynamics that were once enjoyed.
Fear of commercialization: When something transitions into mainstream popularity, it often attracts more commercial attention and may be subject to more extensive marketing, merchandise, and adaptations. Some fans may feel uneasy about the potential for the original essence to be commercialized or exploited for profit.
Sense of betrayal: Longtime fans may feel a sense of betrayal if they perceive that the newfound popularity has changed the essence of what they loved or if the creators or influencers associated with it start catering to the mainstream audience at the expense of the original fans.
Overexposure: Increased popularity can lead to more extensive coverage and discussions about the subject, which can result in overexposure. This constant attention may lead to fatigue and reduced enjoyment for some of the original fans.
In-group/out-group dynamics: Human psychology often involves a sense of belonging to a specific group or community. When something transitions from being under the radar to mainstream, it can lead to a shift in the in-group/out-group dynamics, making some fans feel disconnected or less important within the broader community.
It's important to recognize that these feelings are entirely valid and normal. People form deep emotional connections to the things they love, and change can be challenging to accept. However, it's essential to remember that popularity does not invalidate your personal enjoyment or experiences with something you once loved. Everyone's tastes and preferences are unique, and it's okay for others to discover and appreciate something you've loved for a long time, even if it changes the dynamics around it.
