Nothing to say about the last two arguments, but this:
It is technically theft
…is just bullshit. Theft is illegaly taking a property or service from a person with the intent of depriving them of it. When you’re pirating, you’re essentially making a copy for yourself. In doing so, you’re not taking the original book, nor are you depriving the original owner of said book.
“Piracy is theft” is just some heavily regurgitated nonsense from the early 2000s that has been debunked many times over. It needs to die, because it is just objectively not true.
Not to mention that people that pirate that material are still going to talk about it, so even though they’re loosing one sale to piracy they may be getting an extra 10 sales through word of mouth.
