I really don't see NF micromanaging Meghan's life in the service of a 'lifestyle show' which is pretty insignificant to them.
I don't agree. NF shelled out a huge amount of money on what is ultimately a contract more akin to the 'Studio System' of Golden Age Hollywood - no firm projects confirmed apart from the first docu, but on the basis that H&M would essentially be 'owned' by Netflix for streaming content creation. Afaik they signed it without having to pitch any content proposals, it was a remarkable leap of faith by NF. Somehow during the negotiations they must have been convinced by H&M's reps that H&M were a fecund fount of content ideas, all of which would be smash hits, bringing NF $$$$$ in new subs.
Beyond the prurient pleasures of the tell-all docu, that hasn't happened and the subsequent programmes sank without a trace. With Love Meghan is the last throw of the dice and it HAS to be a success otherwise NF will cut them loose. And NF's judgement will be called into question on their next earnings call. So I can absolutely believe that the contract has provisions relating to promotion obligations on H&M's part, which NF worried that the brutal press around her Games appearance would undermine. Actually for a 'studio system' type contract like that I'd be surprised if there weren't.
TLDR I don't know for sure but I personally find the rumours that NF suggested she leave early to be credible, at least.
