Adobe regularly sends takedown notices targeting pirated copies of its flagship software products but the company doesn't limit itself to newer releases. F-Secure researcher Mikko Hyppönen has had one of his tweets taken down because it linked to an 'unauthorized' copy of a 27-year-old release of Acrobat Reader 1.0 for MS-DOS.I'm betting the notice was automated. It's interesting that the original tweet is still up, which links to here.
