Lots of public sector websites have forms and documents to download. Lots of said organisations also offer a link to Adobe Acrobat for the purpose of reading them.
So, as these bodies are publicly-funded, Adobe is getting both free advertising, and help in cementing their monopoly. The Free Software Foundation Europe is presently lobbying organisations across the continent to remove links to Adobe, and offer a useful page in its place. Link below. I've taken as many references to Adobe down as possible in my workplace - how about you?
