The only one I can see is building culture/name for yourself (which I don't consider a trivial thing), but I can't think of anything else.

Think about this: if Twitter open sources 100% of their code, what would change? Would Twitter clones pop up all over the place? No, because Twitter is the software + infrastructure + name. Most companies think that their code contains some type of secret sauce that makes it special. In reality that's not true. Sure, Google may hide their exact PageRank algorithm, but they don't need to hide their web server code. Or their indexing algorithm. Companies like Twitter are even better for this: they do absolutely nothing that's really proprietary.
For an example of this on a much smaller scale look at TheTVDB (http://thetvdb.com/), their entire site source is OSS, yet there are no clones.
You probably mean this [1], but all I see is this [2]. What's wrong with me?
