This has been my experience with self-hosting too. There are so many different areas of concepts that need to form a cohesive whole. Following a how-to and pasting some commands can lead to something running, but then there are worlds of knowledge to actually understand it. Especially when complexity seems to increase exponentially.
Funny thing is that for every low-level concept I actually learn, the more I appreciate my OpenBSD computer that I mostly play around with otherwise.

It’s not stealing when you willingly allow someone to use it however they want. OpenBSD writes: “We want to make available source code that anyone can use for ANY PURPOSE, with no restrictions. We strive to make our software robust and secure, and encourage companies to use whichever pieces they want to.” If your goal is to polish something like OpenSSH until it’s as good as it can be, the world is better off when robust and secure software spread, also into proprietary systems. When companies use OpenSSH, it does not take away anything from OpenBSD, they are not competitors.
