I'm reading remarks such as "This is no longer FOSS. I want my money back for the book." The anonymous cowards who post remarks like that are either stupid, or they work for a competitor. Changing the license from LGPL to AGPL made iText MORE F/OSS, because now people using iText also have to publish their source code as Free Software. It's only normal that people who want to make money with their software have to share a small part of their profits to allow the F/OSS developers to maintain the project.
License sucks (it's NOT an free or open source license as documented) - company history unclear - intellectual property handling strange - old versions (using other licenses) can not be downloaded any more.
