The part about it not being something many use is probably true in percentage terms. The part about it being used for piracy is hard to prove. Piracy in this context would likely be giving it to others - I personally think it's unlikely.
DRM is unacceptable. If I can't remove it I won't buy at all.
> same. I've bought it. I'm reading it on my kindle, phone, Linux laptop, etc and nobody's going to stop me.
Technically piracy (not that I particularly care). Technically in the USA removing DRM is also piracy, so I guess they're right? Again, don't actually care and would do the same, but I find your response ironic.
The law is pretty complicated though. I think if it's for yourself it's fair use, but 17 U.S. Code § 1201 says otherwise. I'm not a lawyer, sad.
Piracy is ill-defined and so it's hard to say what is or isn't for such an informal term, but even if it weren't: removing the DRM of stuff you purchased legally, and for your own use, is not "piracy" by any reasonable use of the word.
It might be illegal, but it's not piracy.
It even happens with animals of rare breed. They neuter them before sale.
