The only way I can give away my images is through my website, to do marketing FOR ME, not for agencies.
So, this year too: opt-out! Not a single image of mine in the Adobe Stock Free collection, if you want them, you pay! 
the point is NO ONE WANTS these images! i gladly take $4 of passive income for older images that havent sold.
and nothing prevents you from private sales - likely a very different audience
Many photos that I don't sell on Adobe bring me tens of $ on Shutterstock or Istock.

so why not get $ from AS which otherwise would get nothing? it's unlikely to affect your sales elsewhere since they're buying elsewhere but one's buying on AS. how many users shop around when man agency offers images for pennies?
these variousm dataset payments have kept my total income where it was 3+ YEARS AGO.
