Russian plane came apart at just over 30,000 feet

What if the bomber wanted to use air pressure as a part of his bomb on this plane? If it was in a hold instead of in with the passengers, the holds are not going to have the air pressure that the cabin is. So, if a bomb was set to go off at 30,000 feet which is just about where the bomb went off as the plane was ascending, this might be more likely to create "explosive decompression" and much more likely to cause the plane to fly apart in many pieces.

A passenger plane is sort of the opposite of a submarine in that instead of the pressure all being to the outside, in a passenger plane the cabin pressure is extreme inside compared to the outside pressure at 30,000 feet which is about the same at the top of Mt. Everest. So, a passenger plane that is pressurized the way all jet planes that fly at this altitude are is sort of a potential compressed  "Air bomb" to begin with ready to explode if punctured in any way at that altitude and the air going out would tear the plane and rip it along with the speed of the 50 below zero air outside at that altitude or more passing by at likely around 400 to 500 miles per hour. So, being a potential air bomb and the force of the air going by at 400 to 500 miles per hour would rip the plane apart if there were any irregularity to the shape of the normally aerodynamic wings, tail and fuselage. So, decompression of the main cabin at 30,000 feet would also release the air bomb potential of the cabin pressure too and help the plane to rip apart as well.

This is why pilots as soon as there is a puncture or rip in the fuselage anywhere try to descend to around 7000 to 10,000 feet as long as they aren't in the mountains at the time when they explosively decompress from a bullet going through the aluminum skin of a fuselage or a crack forming in the aluminum skin of a fuselage which is under so much pressure at altitude.

Also, by going down to that altitude people can then somewhat breathe and not pass out from experiencing the cold and air pressure of 30,000 feet or more.
