Thing is, it was free, people realised they could use it to share links to chromecast capable apps (that were paid), cue a lot of downloads, then he added direct chromecast support, so cue a further rush of new customers, then bang hit them with paid and kill previous version.
That's is dev prerogative, but the idea is to keep customers, not kind of annoy them.
Its just a move to cash in on the new chromecast app gold rush. Understandable but perhaps short sighted, Soon natural selection will yield less **** free apps and higher quality paid ones, but right now its a 'try anything for a bit o cash' approach. So for me that means I keep hold of my cash and dont buy any paid chromecast apps unless they totally rock.
I think using it for pirating is not main use, gee enough folk use 'shoebox' and avia or allcast for that.
