No its not Haredim. This is an ad for the Amish - "Plain People". This is how the blog "Amish Internet Blog" explains the marketing:
The flyer’s creator knew his audience. Unlike ads for the new Apple product of the moment, this downplays the computer’s tech touting it as “just a workhorse for your business.” It would provide “unequaled safety” because it had “no modem, no phone port or Internet connection, no outside programs, no sound, no pictures, no games or gimmicks.”
Hmm...when its descibed that way, he really could have sold it to the "other black hats".
