Some German officials believe Scientology’s ideology is rooted in a kind of political extremism—a bit of a sensitive area for Germany since World War II. They also argue that Scientology is not a religion but a business, since local churches operate like franchises of the main organization.
How much do they hate Scientology in Germany? Well, aside from a ban (later overturned ) on Tom Cruise from filming at German military site, there was also the following statement made against him.
Thomas Gandow, 60, chief spokesman on religious cults for the German Protestant Church, described Scientology as a “totalitarian organisation” and said that Mr Cruise had become “the Goebbels of Scientology”.
Germany also apparently considered forcing Microsoft to debundle the Diskkeeper anti-fragmentation software from Windows 2000, not for anti trust reasons, but because the company who licensed the product to Microsoft is Scientology-led.
Another fringe religion (although probably a much larger one) getting a lot of attention recently is Mormonism. It is a widely known piece of computer history trivia that the late, great Wordperfect was created by Mormon, and despite the shaky reputation that Mormonism has in some quarters, as far as I know there was never any particular controversy over using software developed by them.
Bonus trivia: Bruce Bastian, one of the two original Mormon developers of Wordperfect, later came out as gay and now devotes his time and fortune to gay activism.
