There are 29000 pieces of debris in LEO larger than a cubesat, and 670000 larger than one cubic centimeter but smaller than a cubesat[1]. While space junk is a problem, a couple of cubesats are not making any difference. Space is big, even LEO, enormously big. Small particles like engine exhaust are a problem (they can cause pitting, etc), not large objects. Or you know, China blowing up its own satellites is also a big problem[2].
