Would authors of a paper be okay with fielding technical questions about the paper (implementation, theory, etc.) from a person in industry?
I see this as a moral grey area because an engineer in industry is in some way profiting off the work of a researcher without necessarily paying them for the time they took to respond to emails, etc. On the other hand, is the researcher responsible for clarifying details about their paper regardless of who they are being contacted by?
Of course, this will vary from person to person and the length of the engagement, but I was just wondering what the general attitude towards this situation is.
