I look at it this way, if I made a copy of this work irl would the person who made it go without their needs met? If I bought it IRL already then it is always fine IMO. If it is a independent person I try to buy it in a way that they get most or all the money and I get files that are not DRM. It really a case by case thing. Like I will never give Nintendo or Disney any money ever again so I have to find ways to get what I want most of the time it is second hand or pirating it.
