It makes me irrationally angry when youtubers do the "X% of my viewers aren't subscribed, so hit that like button!" thing. And I get it. You have analytics, youtube is a hellscape, you need to use every trick in the book.
But I have this knee-jerk reaction that if you're going to obsess over that percentage of non-subscribers, then I will GLADLY be the one to crush you by refusing to subscribe
It's like when a website bitches at me for using adblock. I will enjoy your content, I will support you monetarily if I feel like it, but I will NOT roll over like a dog so that you can get a few bucks of ad revenue
