What is the chance that there is a law-enforcement backdoor? Honest question! Could be anything from "no chance" to "pretty likely" and I don't know enough to hazard a guess. But I believe the answer is important and I'd love to hear what the HN crew has to say about it.
The metadata for files (checksum, filename) is not e2ee so they can access that info and be compelled to provide it when served with a warrant. This is quite a clever twist on a previous theme. The filename and/or checksum might be all it takes to incriminate.
