Yes, but the misunderstanding I'm trying to point out is that Mr Beast is not trying to create something of value, they're trying to create something that works well on a specific platform.

In the Bevy analogy, that would be creating a GitHub project that gets the most stars, regardless of how useful or well the engine itself is working.

I'm instead saying the same thing as you, they should continue focusing on building the greatest engine, regardless of the platform for hosting the project.

If Bevy were to follow Mr Beasts advice, they'd focus on flashy demos, engaging READMEs and so on, to increase the success on the platform itself, instead of focusing on the engine itself, which from following their direction almost since inception, they're doing a pretty good job with already.

For another thing, even if there aren't any other specific effects that are desired, there still might be some that are specifically not wanted, and avoiding those might be important. Mr. Beast is a exactly the type of example that demonstrates this point; by focusing on making the "best" YouTube content as measured purely by popularity, he's done all sort of things that someone might very understandably want to avoid. I agree that he's not confusing, but that's not the issue with him. He's extremely transparent in how little he cares about whether what he does actually helps anyone other than himself (or if he hurts other people in the process of helping himself). I suspect this is quite different from the mentality of most open source developers, who are putting in personal time and effort towards contributing to something that realistically has little likelihood of direct personal benefits for those involved. What you're perceiving as a lack of focus comes across to me as having the humility and thoughtfulness to try to look at the big picture and understand one's actions in the context of a larger environment that isn't improved in the long term by pursuing a single narrow goal to the exclusion of literally everything else.
