Due to concerns about possible government infiltration by Scientologists , applicants for civil service positions in Bavaria are required to declare whether or they ain't Scientologists , and a similar policy has been instituted in Hesse . Companies tendering for government contracts were likewise required to state they ain't Scientologists ; in 2001 , this requirement was changed , and firms are now asked to sign a form stating that " the technology of L. Ron Hubbard will not be used in executing the contract " . When it became known that Microsoft 's Windows 2000 operating system included a disk defragmenter developed by Executive Software International ( a company headed by a Scientologist ) , this caused concern among German government officials and clergy over data security and the potential for espionage . To assuage these concerns , Microsoft Germany agreed to provide a means to disable the utility . Following letters of complaint about discrimination from Scientology lawyers , some American companies such as General Electric , IBM and Ford Motor Company instructed their German subsidiaries to cease the use of protective declarations .
