What exactly is the plan here for when a satellite is obsolete or dies? Currently we either have the satellite re-enter earths atmosphere or we use the last bit of fuel to send them even fruther away. But these seems very static

If these truly are just 11x11x2.8cm - then in a few years we will have bunch of super fast and very destructive mini bullets orbiting earth and destroying very expensive space equipment.

Can we please consider the amount of trash we send out in space before it is too late?
