Oh they definitely got very VERY lucky in the beginning because they were among the first to start doing the park vlogs an between the parks an what's on around Orlando they would have gotten nearly all of their subscribers, but now most of those subscribers probably don't watch but just haven't unsubscribed or are now inactive, if YT done a clear out of inactive subs they would drop thousands100%
They got lucky with their early success of the channel but they have no desire to grow or make their channel better. They should keep up with social media trends but they are too lazy to do anything other than point and shoot their camera while Jenn splices the footage together. This was fine 10 years ago but now many 15 year olds with an iPhone can produce better content than the Trackers do.
They have their loyal Stan’s who will watch no matter what but their channel will not grow. Subscriber count has been stagnant for a very long time now.
But give it one day an most of these viewers will grow up, I still think the vast majority are kids/teens who haven't had to work for what they have because of parents, wait until they all have to work an pay school fees, they will soon see how wasteful the slacker are when they are struggling to pay for food
They are honestly playing a dangerous game with not trying to keep the channel growing, an it's going to bite them in the ass one day, I've seen YTs who had been successful with over 1/2/3 million subs an getting easily over a few million per vlog every vlog completely crash an burn an are now lucky to even get 100k views because their audience simply grew up an because they had been successful they didn't bother trying to keep growing the channel to bring new subs in
