This is bullshit and untrue. We contribute back our changes to open source all the time via https://cloudflare.github.io/ https://cloudflare.github.io/. We upstream where people will take our changes. We directly pay open source developers (take a look at all the money we paid to Mike Pall for LuaJIT) and employ/employed people working on open source projects (e.g. OpenResty). Over years we've been contributing and explaining how we operate and open sourcing the relevant code (just look at the series of blogs by Marek Majkowski and others talking about how we fight DDoS and open sourcing the tooling).
