Torrents are very inconvenient compared to many streaming services.

Therefore, you would expect most people to opt for Netflix. (And by and large I'd expect Netflix to be more popular in mass than tormenting at this point for places where it's available.)

But what if it's not available where you live (That's inconvenient), doesn't have the content you want (That's inconvenient), or you want a file you can play offline that isn't allowed to be downloaded on the Netflix app?

Convenience wins almost every time, but not having the option to do something (be it for lack of $$$ or availability) isn't convenient so that's when more people turn to piracy.

Far more convenient when you consider that Netflix's catalog of reasonably mainstream as-seen-in-theaters movies has been shrinking for years.

As the end user I don't care "why" their catalog has been shrinking, I only care that something I watched last year and want to watch again is no longer available on that service.

And no, I'm not going to sign up for a dozen different services just on the off chance that one of them will have what I want to see at any given point.

In my experience in the last five years, Netflix's batting average for actually hosting movies I want to see is around 20%. In terms of convenience, if they don't have the movie at all it's kind of like dividing by zero.

No but it is more convenient than lesser known streaming services like popcorn or certain kodi plugins that don't work well.

Depends on what you want to see. If Netflix has it in your country in your language of choice: Netflix wins, else BitTorrent wins.

No but there are piracy streaming apps that are more convenient than netflix.
