Hi, I'm Alex, founder of Destroyer.io. I was just tipped about this HN thread, I had posted one, and had been answering questions, here - https://news.ycombinator.com/item?id=8074934

We don't expect this to be a problem. The interceptor would be breaking several laws. Even if you aside that breaking the law is not a problem for them, there are far easier and less expensive ways to access your data. Like accessing it through your internet connection or breaking into your house.

Either way, all of your guys' concerns are valid, and I understand your point of view. We'll grow and improve our messaging + service as time goes by, that's for sure.

Thanks for sharing your opinion. Cheers!
