Then why don't you do that? If you are happy with just using Paizo modules in 5E, then just do it. WotC would probably be THRILLED if you were playing 5E using Paizo adventures.
They *don't care* if you aren't giving them any money. If they needed the money, they'd probably be producing more stuff. But since they aren't... ipso facto they don't NEED the money from new product to keep the D&D department active within WotC. All they care is that you are still playing 5E... because that means there are other people at your table playing 5E, and will maybe go out and buy some 5E product at some point, or go to dndclassics.com and buy some PDFs at some point, or go off to run their own table elsewhere and maybe THOSE table's players will go out and buy some 5E material too. That's really all that matters. People playing 5E. Not the money coming in from the sales of 5E.
Your money... Sailor Moon's money... the money in Sailor Moon's wallet... they don't want it. Because they apparently do not want to spend the time, effort, and finances to produce the thing that would GET the money from Sailor Moon's wallet.
Regardless of how many threads you start bemoaning the fact.
