It is open source tho is it not?
Discussion
Just because it's open source doesn't mean that they are running that code on the coordinator, just as nothing guarantees that signal's servers are running the same code they have on GitHub.
The only way is to run it yourself.
True they are *planning* to decentralize the coordinator, if that were to happen then we could be more confident that the code the coordinator is running is the same, right?
