They are liars, shady business, IP violators and are downright dangerous.
They have all those great offers for you, but they refuse to give any details as soon as you ask any question. More than half of them are "the biggest in the world" (sic). They lie about download numbers, about download size, about number of software actually installed and about their connexions. They even lie on the actual payback price.
If you refuse, they build special websites, copying yours, with your IP and trademark and register adwords with your name, in every way possible.
They also resell their solutions/websites to other people, using "Affiliate networks", so that once you take one down, 20 appear. And the guy who you took down had no idea who you were or what the software was...
They also have deals with download.com/softopedia/softonic to change/rewrap your installer, without your agreement, often violating your license; or they give back money to those websites, so they are ranked higher than normal other downloads.
And of course, open source software are never respected.
I believe OP is very polite: There are no good reasons to not shame them publicly.
