@matt I have a feeling that cassette shells intended for pre-recorded tapes never had tabs to start with - the write protect notches were already open (they weren't recorded on anyway on a cassette machine but filled up with prerecorded lengths of bulk tape from a duplicator)
@matt they were on an indie label run by one of the band members (which still exists today, though they lost the rights to the Dead Kennedys music in a lawsuit in 2000s) who have always made political statements (the tape duplicating company wouldn't care what was on the labels provided they got paid)
@vfrmedia I dunno, with a message like that I half-expected it to be a few dozen copies put together in someone's garage. I'd think a label with the capital to produce thousands of tapes would be too corporate to allow one of their bands to do that
