No idea how accurate this report is. Either way people online tend to be a vocal minority. The vast majority of people using Netflix either aren't on Reddit or other discussion forums, or are simply lurkers who never comment. I find that people that do comment tend to be doom and gloom when it comes to these sort of things. That applies to me too, as I certainly won't buy Netflix due to their content.
But Netflix is large enough that it will probably be fine for quite some time. Even so I do think streaming is declining rapidly due to too many services and studies have shown that people do pirate more when accessing content becomes tedious. It's all a matter of comfort.
