That is a non-sequitur. Investigators should have access to accident data regardless of whether the pilots did their job.
Root cause analysis isn't the only reason: it would be good for pilots to have this case study, as well as analysis on how systems responded to the abrupt change.
Having this data is strictly better than not having it.

Yep, could be used as a "this is exactly what you do in this scenario" example for future pilots, or a "what did they do wrong" type real-world exercise for pilots to review (with no blame given to the OG pilots in this scenario for example).
Middle ground would be to have full media access for investigators, but a union rep managing a review and redaction process to have anything immaterial to the investigation redacted. This preserves both valuable data and privacy. Checks and balances.
