I'm just guessing but it might have to do with the concerns raised by the first commenter in the reply by textfiles (Jason Scott) in that reddit thread

tl;dr seems to be they received a massive (71,000 tapes) archive that hasn't seen any activity or communication in 7 years.

If you read further in the thread, you'll also find other concerns about Jason's reliability

Yeah, it's a nail-biter.

Well they do kind of seem like reasonable concerns, though I'm assuming/hoping there's more to the story.
