Both are only late 30s/just past 40 with two young children. Meghan is smart but clearly has her hands full with the kids. Harry is only average at best, and just born into immense wealth and privilege. It would be insane to expect them to keep all the balls in the air. The crash is inevitable and long belated.
A lot of their "work" is quite insulting to professional authors, artists and media creatives. A writer will spend years solely working on one book. A filmmaker will only work on one documentary. H&M somehow manage to knock out books, podcasts and documentaries simultaneously which means none of those projects have received their full passion and attention. The massively delayed schedule for the podcast probably indicates there were just too busy to dedicate their full attention to the project...a pisstake for all true journalists who can only dream of such a deal with Spotify.
Their brand is beyond salvation to be honest. Especially after the non story of a 2 hour car chase in NYC traffic that has not been taken seriously by any media outlet. There are no followups corroborating their version of thee story (CCTV, eyewitness accounts etc) so the whole thing just ended as a manipulative half-truth.
