Netflix has had a spectacular growth in the last few years. Partly because the great content, and partly because Netflix policy on how users can enjoy the service has been pretty lax.
You can share your monthly subscription with others (not necessarily your relatives) and until last thursday, you could use proxies to access Netflix from other countries that had no access to the service. That was the case where I live in Spain for many years, but last october Netflix finally was available here.
In the last few weeks we’ve seen how Netflix has announced a global expansion. That shows clearly how mature the service is, but that ambition coincides with the decision to ban proxies, even if users don’t care about that. I suspect the sharing policy will change too soon enough.
Piracy was good until popular again. It has been so with several software platforms, with music services, with console games, with YouTube -as Alex pointed out– and, of course, with Netflix.
