 Due to concerns about possible government infiltration by Scientologists , applicants for civil service positions in <unk> are required to declare whether or not they are Scientologists , and a similar policy has been instituted in <unk> . Companies <unk> for government contracts were likewise required to state they are not 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 <unk> 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 <unk> these concerns , Microsoft Germany agreed to provide a means to <unk> 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 <unk> to cease the use of protective declarations .
