I know that some developers are smart enough to collaborate with piracy instead of trying to fight it (which is pointless). They make 1 or 2 update buffer, which separates patrons from, let's say free users. So if you are subbed, you just get a more recent version earlier, while others will have to wait for month or so. If artical decided to do something like this, then making free use version a very first one is a fucking bad idea if you ask me
.
Also, there is a demo posted in xwitter if I remember correctly, so maybe they just use it for this purpose.
