Your frustrations with streaming services are very relatable and I completely agree that the space has become increasingly fragmented. I, too, have cut down on some subscriptions where I feel that I don’t get my money’s worth.
I believe your case is a perfect example of intellectual property theft: your 40 customers are paying you instead of paying the copyright holders. If you hadn’t offered them with this solution, it’s not unreasonable to think that they would be more willing to spend that money on purchasing it directly from the legitimate owner. Consequently, it can be argued that your shared library is incurring damages through missed revenue. By extension, even by an iota of a percentage, the service provider or the production studio will need to recoup that in the ways I’ve mentioned.
So while I completely understand your rationale for pirating, surely we can agree that in cases like these, there is some—no matter how little—degree of legitimacy to the assertion that piracy is detrimental to those of us who pay for our subscriptions.
