Should we be !?

That is what I'm asking.
They have 700.000 photos at the moment meaning they payed approx. $170.000 for them (assuming they paid for all).
BTW, did anyone notice they are offering free subscription trial?

In order for you to appreciate simplicity of our services we offer you Free trial is based on a Subscription Plan.
It lasts for 14 days and allows to download up to 10 images of L+ size (2600 x 1800 pixels) per day.
You will get up to 140 images absolutely Free of charge! It is as good as a Free subscription for 14 days!
I just hope they are paying us for these free downloads. I would assume they are (I guess it would be illegal otherwise).
