I don't particularly care about any kind of "tech community". But the thing you seem to be missing here is the following.
Linux is not a "product", and it doesn't want to take over the world. (Although, for such a bad approach, Linux - which in case you missed it, is just the kernel - is absolutely everywhere these days, from servers to mobile phones. So much for a huge problem. Even MS hasn't managed to do this despite their desperate attempts.)
Linux is not an OS. There are thousands of distributions which aggregate thousands of packages around the Linux kernel to provide something that looks like a traditional OS, but the model is completely different. And while it's not as polished in some areas as any commercial OS, it's more in others.
Why should it take over the world? Why the heck would you like it to be just like Windows or macOS?
If you like what MS and Apple do, just buy their products and leave the open source stuff alone. I don't get it.
Who cares about it not being for "normal users", whatever that means. Normal users do use Linux all the time with Android, in case you didn't notice. Android is an example of something polished around the Linux kernel. But it's completely controlled by Google.
If you want a desktop OS around the Linux kernel in the same vein, you'll get the same thing. Something only an organization such as MS or Google would come up with.
No kidding that most people actually involved in anything around Linux don't want that, ever.

Meanwhile, Linux - again it's the kernel - is running on more devices these days than Windows ever has.
