I think it's about how much delta v required to de-orbit vs. park. For
LEO sats the DV is smaller to deorbit vs. park. For sync sats, it's
just about getting it above the very valuable sync orbit. So a small
increase in orbit is not much fuel. For lower than sync, it's a lot of
unused space and a long way down to deorbit so they usually stay where
they are.

I think the best practice right now is to save enough propellant to
boost your old satellite into a parking orbit. The idea is we spent a
grillion dollars putting it up there, and someday we might harvest old
satellites for material rather than launching new stuff for a grillion
more. You'd have to burn propellant to de-orbit too, so if you're
going to keep extra gas on the ship then you might as well use it to
park instead.
If Elon Musk wants to waste his own grillions by letting them burn up
in the atmosphere, then he can do that.

is there any accountability for debris left in space? like littering
tickets? why hasnt somebody like elon musk made a space roomba that
just goes and pings each item out of orbit back into the atmosphere
since we know where it all is

I have this vague recollection that we currently can't even track
all the
space junk. There was some lower limit, in the order of
inches(?), below
which there isn't enough of a radar(?) return.
All I want to know, how long until Kessler syndrome? :)

Just because I know a bunch of you guys are interested in space
stuff. Check
out this really cool site that shows every object in orbit around our
planet.
