i can, sadly, agree. i noticed it too
there are several echoes of heaven pdf around the net:
campaign, the last free city and adventure seed 1b
at least they are all for d20, but maybe from the "selling" point of view this worst since d20 probably sell more.. or at least it did since the newcoming of 4th ed.
By the way.. piracy is a matter of respect of the work of others, free culture and free-something is kinda bulshit when behind what i download there are HOURS of time.. want free stuff? take low quality one or stuff made to be free!! guild companion for example provide ton of high quality FREE material, that should be enough for those that don't want to use their money
I can only understand the download of a piracy PDF if i just have to take a look at it before buying, this problem doesn't exist if i can take a look at one in a shop or reading several good reviews to have an idea of what i'am going to buy!
