Digital Rights Management is there for a reason. I work in publishing and know why it’s there.
With all due respect, I think the reason it’s there is to make more $$.
Publishing companies have been incredibly greedy when it comes to digital versions of these things. Here’s an example: I can buy a $10 paperback which probably cost various companies about $7 to print, bind, ship, store, shelve and sell. I can then take this book, read it, lend it to an unlimited number of friends, and when I’m done I can sell it for $1 the next time I have a garage sale.
OR, I can buy a $9 digital book from X digital retailer which probably cost various companies less than $0.01 to list on a website. I I can’t lend it or even resell it when I’m done.
Digital publishers (of music, games, books and films) are trying to do these things with the digital market:
- Eliminate the used sales market - some publishers even look at sales of used copies as “stolen sales” even though it’s legal practice and common sense. (Hence the move to subscription services & DRM etc)
- Sell a far cheaper digital object for the same price as a physical object with a MUCH higher profit margin.
- Limit the versatility of a digital object to protect sales (sometimes this is legit (see # 4
other times this is stupid and greedy, like when they had Amazon take out the ability for the kindle to read the book to you, because they want you to buy audiobooks instead.)
- Fight a “sharing is not stealing” culture. IMHO, this is the ONLY legitimate reason publishers have for thinking about DRM. Unencumbered digital goods allow you to make unlimited copies at close to 0 cost and distribute them all over the world. Obviously, this deprives an author/musician/artist & publisher of legitimate revenue as they like anyone else are entitled to be paid for their work. Also obviously, if you are not removing DRM in order to share, this doesn’t apply to you.
Anyways, back to the OP’s question…
No, it is not sinful to remove DRM from your Kindle eBooks for personal convenience provided you are in a jurisdiction that makes format shifting legal for personal use. It’s like if I bought a hammer that came with T&C that only permitted me to use it on nails purchased from the same company. I would feel not a shred of guilt for using it with other nails. I still legally paid for a book; and I’m legally entitled to read it the way I’d like.
I’m not an expert on UK law, where you mentioned that this sort of thing is broadly illegal. I’m also not an expert on whatever Catholic documents might pertain to this (I’m currently discerning a call to the Catholic church.)
Based solely on what I’ve elaborated on above, the question you’d need to ask is whether or not God requires you to obey the government when they’ve created a frivolous law to support the greed of certain institutions. IF removing DRM is sinful, it’s ONLY because Christians have a duty to uphold the law and that’s the current law. It’s certainly not because it’s inherently wrong, especially in the scenario you described, and I sincerely hope the laws of your country change.
