When it comes to trust, it's easier for companies to trust big companies like Github than it is to trust a random person who decides to provide code hosting.

You could even go dirty and write a blog post compiling Github-related SJ controversies, then suggest that they aren't a reliable place to host your code

Even if someone buys that argument, hosting with Atlassians Bit Bucket would make more sense then to host it with a random place. Businesses can be attacked for hosting their code at NRxhub.com and suffer PR damage.

I could imagine a trustless solution that works by doing decent crypto to draw an audience but wouldn't expect a simple solution to do so.
