The reason why the competitor is so far ahead is that they installed the Widevine CDM 4.10.2710.0 back in October, when it first came out, and then started working on cracking it. I asked StreamFab's Project Manager to do the same in November and was told that the old CDM was good enough. I'm not here to blow my own horn, but this is not the first or only time when I've advised them of a fix that needed to be looked into and was ignored with disastrous consequences. The same has occurred with Jack occasionally.

afaik they use Playready L1 CDM API not chrome cdm and its far more complex to get it, also take in mind streamfab probably bought the chrome cdm method before and didn't crack themself. All these cracking stuff require lots of money or very high skills, or sometimes even both at same time
I have nothing against dvdfab or streamfab but you can clearly see the way how they are operating their business is odd, there is a ton of clones for streamfab software under differents names/websites but its the same company, Competitor don't act like that and seems more serious/professional on that part, also probably way less greedy.
But as we can see overall P2P and scene groups (always) are still ahead for the tools/API if you ask me compared to all these paid sofwares (as they can get 1080p netflix stuff), still 2160p netflix is very private atm even for them.
