There’s a flip side to this which is building on top of which solves your problem but aren’t actually suitable. It “works”, but often at the expense of someone else. A great example is homebrew and GitHub. Or, making a shim between something that solves 80% of your problem rather than solving the problem yourself. The mark of a 10x engineer IMO is getting the build vs buy question right consistently. My experience is that teams get it wrong often in both directions
