Just recently someone unsubbed my channel, am I heartbroken? OF COURSE!......not. People change and your content changes, at times you just grow apart and the person who once thought your content was great now has lost interest. Is this something to get butt hurt over? I don't think so I am okay with someone unsubbing from my channel because in reality it is the views that matter in the end. If they aren't interested in my content they likely aren't consistantly watching it and thus aren't a viewer anyways. This all kind of goes back to creating a FanBase OVER a SubBase. It is vital to have fans that love your stuff if they unsub it just means they aren't a fan which eh do you really want someone you doesn't like you watching your videos anyways?
NOW a slight disclaimer, if you make a major change to your channel and there is a significant amount of people that unsub, I would look at maybe seeing what the change was, if you personally liked the change, and if losing subs over said change is worth it.
Good practice is to constantly review your channel and pay attention to the direction you are going, having a clear vision of what you want in a channel is key to staying on track. If you go a direction that gets an undesired result and if bothers you enough change directions. Remember Youtube for most of us is about entertaining and interacting with other people, as the old saying goes "The Customer is always right."
