What point are you trying to make? That because of the existence of Nginx, every other HTTP server project should be abandoned?
Nginx certainly is some kick-ass piece of software, but as every other software, it doesn't suit 100% of users 100%. There are valid reasons to choose different HTTP servers over Nginx, as people in this thread already pointed out.
To give another example, the OpenBSD project, famously obsessed about code quality, recently removed Nginx from the base system, not least because they think its code is "über-optimized," possibly eliminating OS-level security mechanisms. [1] This doesn't mean that the code bad, but some people prefer "tiny" and clearly-written codebases that can be audited in reasonable time. thttpd, in particular, seems to hold the balance between code size and performance very well, which makes it a nice choice for embedded systems.
