It's an attempt to move the digital world into the analog world. As a regular human having a quick throwaway conversation with someone, I'm not going to remember it weeks or months down the road. The same thing with digital. Signal has the same feature.
I'm failing to see how disappearing chat that is on by default differs from in-person conversations. If I have a video call, I'm not required to record it. If we have a meeting in-person I don't need to either.
They will have the conversation off the record, and if text isn't available it will be a call or meeting instead.
I'm saying that disappearing chat that is on by default is (trying to be) like in-person conversations. So it's easy to interpret person A's request to take the conversation off the record as evidence of a conspiracy, but maybe just just don't want a record of what they're saying because it's weird if I took a video recording of every in-person meeting I've ever had, and that weird feeling holds true in the digital realm as well.
The issue here is not having an off-the-records conversation, it's saying that they want one because they're about to talk about something that would embarass legal.
