They seem to have plenty of resources to get Goodman Games to reprint old adventures and in the DMs Guild era do they even pay contractors in advance now a days?
Reprinting old adventures doesn't involve all the things that new products built for 5e involve. They don't market and do PR and do playtesting and editing and so sooo many of the things involved with a new product.
Face it, it IS an expenditure of limited resources. They can't just authorize 10 third party products and pretend it costs no limited resources. They all cost them something, and I want those limited resources focused on something else. Why is this such a problem with you?
And yes, when you hire out the writing (and it's usually just the writing and artwork, and no other aspects) then yeah you pay them in advance at least a portion.
Now if you want DMs-guild stuff, that is a different story. But you could write and sell a FR Campaign Setting book right now for the DMs-guild.
