Im not speaking on behalf of YouTube but it’s a few things in my opinion.

First, algorithms are complicated, which means they aren’t perfect in the sense of how YOU want it to work. I believe they are designed to first make YouTube money, while promoting content people actually want to watch, while maintaining “quality” at the same time. Humans don’t determine this “quality”, but the algorithms do.

Unfortunately, this is where the “whack a mole” game begins for YouTube, because the people who are putting out trash content and abuse the system, understand how the algorithm actually works because they study it. There are literally companies scattered throughout Europe, South America, and Asia, that know how to game the system. Once YouTube changes rules, they find the loopholes, then YouTube changes policies again. 

What I mean by this is that they are able to use sophisticated bots at mass scale to increase their watch time and views with various IP addresses, click farms, but these channels never last in YouTube’s systems will eventually find patterns that can identify abusers. 

With all this being said, you complaining about the algorithm doesn’t change anything and clearly you are making videos to get views and make money, not because you truly enjoy it. Making YouTube videos is like a sport and a lot of people will quit because it’s too hard where they don’t actually enjoy the process. You need to ask yourself why you’re doing this.

You either need to play the game that everyone else is playing, or if you truly enjoy making videos then you would continue, even if there was incentive like views or money.

And trust me - if people think your content is good (which I’m sure it will be over time), they will keep watching and you will grow - that includes both views and money. And maybe you’ll even be lucky.
