I find this very strange.
Blackrock, Disney, Marvel, these are all public companies. These are all owned by investors. Investors don't like seeing wastage or losses. Public companies can't simply find "money behind doors" without it leaving a big paper trail.
Blackrock is an investment company, their entire mandate is speculation on future earnings. Even things like ESG can be seen in that lens- it's a long term strategy to force markets to be what they view as more sustainable. I disagree, but ultimately if you believe that climate change is a big issue you'd want to solve it so that your money is still there 50 years from now.
Blackrock is not just shoveling money into films that fail because they hit diversity targets. To do so, they need to either buy up IPOs or just discharge money into projects that have no return on investment. The former is just normal investing, the latter would be a direct violation of fiduciary responsibility- not only would the executives lose their licensing, be barred from practising in finance ever again, have large fines levied against them, etc, the same would be held against Blackrock itself due to the fact it was corporate policy rather than just a rogue board. In effect, Blackrock would end up disgraced and probably go into administration because their whole remit is investing, and that would be off the table. The investors and creditors would then be compensated with the sale of all assets in the company.
A much saner explanation is simply that these individual film companies, which make hundreds of films each year, can simply use the revenues of blockbusters to fund any losses from wokeshit, if those films even do have losses, because many don't. "Get woke, go broke" is a nice rule of thumb for individual projects, but it's not a law of the universe, many do go on to be successful, and the "broke" part only applies to individual projects. There's no scenario in a million years where Ghostbusters 2016 bankrupted Sony.
It's not unheard of for companies to be doing shady shit and having it not revealed because investors are incredibly happy with the book reports, but the kinds of things here require big evidence. Most investors don't bother reading financial reports, but they are publicly available, by law, and must be issued annually and (usually) quarterly. You could easily see any shady shit from a glance in them. I'd encourage anyone to read them if they're interested because they usually mention potentially damaging issues in their financial reports even when there is monetary value on them, eg: Activision/Blizzard talks about their lolsuits and sexual harassment allegations. ESGs and diversity would probably be at the very start of the reports for Blackrock because that's something their pushing- they'd be proud to state that they're intentionally bankrolling failed investments if it were happening.
