I'm late to comment, so I may be typing into the void.
I understand the admin's decision to limit their exposure to legal risk. I had similar experiences as a small business owner and you would be surprised how quickly most people's idealism is tempered by the risk of potential legal action. It's totally possible to believe strongly in the legality of something and its benefit to society (in this case piracy) and still choose to limit your own legal exposure. As far as I know, none of us paid to be here, so the polite thing to do is say "thank you for hosting us" and move on if it's not your thing (or just make a second account).
I believe our current copyright/intellectual property scheme is broken at best, and designed to fuck us out of every bit of culture that has ever existed, at worst. Piracy exists because the system is broken and the industry is entrenched and refuses to adapt to customer demands. It screws music fans, artists, and probably the individual low-level employees of many music industry companies and organizations.
Greed ..... it's the cause of all these issues. Greed on the part of the corporations and industries that run these services and own all this content.
If they just tempered their greed, lowered their costs, paid themselves less, shared profits with those who actually deserve it and made all of it more affordable and even cheap for customers .... no one would think of piracy and we would all just feel comfortable paying for services and content knowing that the money we did spend was being shared fairly.
Instead when we all know that the profits they make just go towards corporate greed, giving away money to shareholders who do nothing and give little to no money to the actual content creators while artificially inflating costs on all of us just to squeeze more out of everyone ..... those of us at the bottom really don't mind pirating content because we know that the only people we are stealing from are the greedy idiots that instead feel that it's normal for them to steal from us.
Everyone pirates everyone else .... it's a matter of economics ... either we pirate them ... or they pirate us. If we all live with an understanding, we learn to live in balance without pirating one another.
Right now the they're tilting the balance against us ... which is why so many feel obligated to raise the Jolly Roger once again.
