Up until now, I have been reluctant to weigh in on the streaming-vs-encryption topic due to the strong feelings on each side, but I'd like to explain why I host feeds.
I stream because I enjoy the hobby and want to share it. I don't do it to "keep law enforcement honest," I don't do it to be a thorn in the side of public safety, and I don't do it to try and embarrass public safety. I've actually received a few comments from people in public safety thanking me for providing the feeds, and some of them have provided me with information - nothing proprietary or confidential, however - to improve the feeds.
Yes, the feed providers receive the incentive of a free RR premium subscription. In my case, the money I've put into my feed equipment, electrical usage, and Internet access will never be recouped in free premium RR access - so the incentive is really a moot point for me. If it was about freebies, I'd come out way ahead moneywise to drop the feeds, sell my equipment (at a loss), and pay the annual premium subscription fee. I suspect that a lot of other feed providers would agree with me on the freebie point.
With respect to social media, I am not on any such media - and that is by design. No "likes" or "retweets" for me! My feed descriptions specifically ask feed listeners to not post what they hear on the feeds to social media. Does it work? There's no way to know with certainty, but I can say that to the best of my knowledge, there has not been any mention in my local news media about streams of public safety agency radio traffic.
All of that being said, I understand the argument that streaming of feeds to share the hobby is destroying the hobby. I've read the arguments on both sides, and I've read the news reports of agencies choosing to encrypt their radio communications because of streaming. However, I have a hard time believing that streaming is singlehandedly driving agencies to encrypt their communications as a means of protecting agency staff because far more than encryption goes into staff protection. I am also of the opinion that absent streaming, many agencies would find other reasons to encrypt their communications; some agencies simply don't want anyone listening to them, and they will say whatever it takes to get there.
Further, I'm of the opinion that the immediacy of social media, hashtags, and text messaging make a significantly larger contribution to the endangerment of law enforcement than scanner feeds - the riots in Ferguson, Missouri being an example, yet we don't see anyone demanding the end of social media, hashtags, and text messaging. In addition, social media can be and is used to attack law enforcement on a daily basis in ways that feeds cannot be used.
I've said before on these forums, and will say again, that I have no issue with the encryption of tactical/surveillance/car-to-car comms, etc. frequencies/channels/talkgroups. I understand the purpose of those things and believe that encryption should be used as needed. I do think that dispatch should be in the clear; I fail to see what is gained by encrypting communications regarding a traffic stop for running a red light (for example).
I realize that what I've said here will probably not change any minds, and I don't think that arguing over streaming is going to move the needle for/against streaming to any appreciable extent.
I've spoken my peace here and will not speak of this again.
