No. I simply find them easy to use. Maybe it’s because familiarity, but I see nothing inherently difficult with saving a document as PDF, and making them form-fills with the right software isn’t too hard. When someone is sent a contract or something they tend to be used to looking at what they would see on paper, PDFs tend to be what they’re used to and very basic WYSIWYG, so people don’t have to think too hard about it.
