I've been a victim of this too and it sucks. People will flat out copy your business, and while they're at it, they'll go and copy and paste your painstakingly-written documentation as well. This really leaves a bad taste in my mouth.

I always try to go with the OG when I find these types of instances, since they're likely the one actually innovating (I know nothing of FireHydrant, so this is just conjecture).
