How legal is Alleycat Player?
I have no fucking idea. The law is clear as mud on the issue of scraping websites. If it is public information (that is, not protected by a password) then it is probably safe. On the other hand, scraping gigabytes of data could trigger a response by the target, as in this case:

Then there is this app which mimics the Instagram API and has been removed from GitHub:

While Alleycat doesn't do anything on this level (it only scrapes for video data), it certainly does some amount of mimicking, especially when it uses the Local Proxy Server to fake the referrer. I suppose if Alleycat were to get wider recognition, some attempt could be made to shut it down. That is why I encourage people to copy and reuse the code.
There is a long-standing campaign to take down Youtube music rippers:

Just posting information which leads to piracy can get you in trouble:

In Canada, there are safeguards in place to block copyright holders from abusing legal loopholes:

Back in October, there was a big shutdown of pirate sites (Openload, Streamango, Verystream and Rapidvideo):

Openload was the big 800-pound elephant. It was nearly as big as Netflix. However, as you can see from the offerings in Alleycat Player, there are still a lot of sites still available. Perhaps they just aren't big enough yet to bother shutting down? Some sites have been shut down in places like Lithuania and Malaysia but they were a lot bigger than you would expect. In those areas of the world, the draw is Hollywood films dubbed in the local language. The potential audience is huge.
As for IPTV, there have been too many takedowns to count. Sellers of set-top boxes have been hauled into court and sued for millions. Other sites have given up their user logs to the authorities but it is highly doubtful that end-users will be chased down. This, however, is worrisome:

Most of the IPTV sources in Alleycat Player are legit because they are available directly from the horse's mouth. The questionable links are all in the US, UK or Canada but I actually have no idea how the suppliers of those links stand legally. They've all been in operation for at least a year.

I'll post more articles as I find them. This is obviously of special interest to me.
