If it's "their job" they really really suck it after 15 years.
A job to me means you answer to somebody. That could be a boss at a corporation or customers if you own a small business. At best they've just lucked into a long running gig where they get paid. And if they actually cared about their "fans" or "customers" or whatever they would deliver on simple promises, produce a higher quality product and even say when they are on break. All simple things other YouTubers do easily.
This part here stuck out to me:
Their job isn’t one where they can go home and stop working. They are constantly working. What if you went to work and you got emails or messages all day telling you you’re doing something wrong, putting you down for one thing or another, telling you that you’re not doing things fast enough etc. I guarantee it would get to you eventually.
That's exactly how my job is and my husbands. Many, many people don't just "go home and stop working".
I do not have set work hours. I work on my projects when I work on them. If what I do isn't quick enough or isn't correct or isn't satisfactory to my clients, I hear about it. While some days are more frustrating than others, it's what I signed up for and these are the boundaries that I have set up for myself. I do what I'm asked, when I'm asked to do it and I do it well. I also make damn good money for what I do, so for me, it's worth it.
The same goes for the Trackers. They do what they want, when they want it. They make damn good money for what they do. They can choose whether or not they listen to customer feedback. But their success is dependent on their customers enjoying their work, so they should care. They've set their own boundaries. It's not anyone's fault but their own that they did not draw any boundaries between their life and their work. So, they deserve all the
tit they get for putting what they do out there.
