Reminds me of when a Hostgator employee told me on reddit that he liked digging through peoples' websites and chatted with me about the stuff I had hosted on my website.

That's potentially different, to be fair. Websites are generally made with the intention of making them public, and unless you're digging through stuff that hasn't been made public, there's nothing wrong with browsing your customers' websites and talking about it. (Of course, maybe that's what the Hostgator employee was doing - in which case, shame on them.)

On the other hand, I'm pretty sure that the person who installed Huntress did not intend to upload any info at all, let alone to have that information made public.
