BlackRock employs a stable of former policymakers, underscoring the importance the company occupies in both financial and policymaking ecosystems, in something akin to a shadow government entity.[157] Good government groups have documented 118 examples of “revolving door” activity by the company—cases in which a government official joined BlackRock’s roster, or vice versa.[158] In one particularly troubling example of how Washington’s revolving door operates, in 2017, a former BlackRock executive was put in charge of reviewing the FSOC’s work for the Treasury Department.[159] Unsurprisingly, the Department’s conclusion was that FSOC should “prioritize its efforts to address risks to financial stability through a process that emphasizes an activities-based or industry-wide approach,” the company’s preferred position.[160] This conclusion all but ensures that BlackRock will not be designated for greater regulation by the FSOC under the Trump administration.

If you kill ffmpeg process it will exit with code 255 (easily reproducible in the terminal)

Both kill with a job specifier and terminal signals send to the entire process group, so both the shell and sleep.

rkill command from pslist package sends given signal (or SIGTERM by default) to specified process and all its descendants:

Why then sending the SIGINT manually to the shell doesn't kill the child, e.g. 'kill -2 <shell-pid>' doesn't do anything to a child process while Ctrl-C kills it?

Quit the program by sending a different signal to both processes, e.g. SIGQUIT with Ctrl + \.

Be smart about killing and moving; if there is a closed fold, act on the entire fold.
