I had the opportunity and honor of discussing this with a good friend yesterday evening. He took the "ban it" side to begin with and he and I beat this thing every which way we could. In the end, here's what we came to and both agree on. This bill is worse than nothing. Leave aside all the hyperbolic statements and straw men meant only to demonize others for the sake of self-aggrandizement; the bill does nothing.
Allow me to elaborate. The bill would ban the sale of coordinates for hunting; fine, change the purpose of the app to wildlife viewing and put in a proviso that said the use for hunting violates the purposes of the app. Law defeated. The bill exempts out guides and outfitters; they can use it for whatever purpose they want, and you cannot ban the use of GPS coordinate data to guides and outfitters or to be used by their business because you then prohibit them from using a GPS at all (which would be stupid). Further, all the app company would have to do would be to obtain a guide/outfitter license, or work through a guide/outfitter, and they continue on their business as if the law never existed.
The bill, at best, is poorly crafted and poorly worded. At worst, it's a knee-jerk reaction based upon emotionalism without considering consequences or alternatives. We didn't even get into the landowner exemptions or lessees, but that just adds yet another end-around. At this point, I cannot see any actual benefit from this bill or from supporting the bill other than a self-aggrandizement "look-good/feel-good" angle, or as a means of protectionism for guides/outfitters. There can be a lot of language thrown around about trying to prevent the boogeyman from eroding this, that, or the other; but where reality sets in, the bill does nothing beneficial.
And, yes, I used to be supportive of and involved with BHA. No longer. I agree with Ryan Avery's take: some of the state chapters do great work, but that's as far as it goes.
