This is a dodgy dot point as I see it. Planck and Einstein had some similar views on the whole social/political impact on science thing - they both believed that science ought to be pursued in and of itself, as opposed to Ernst Mack. It's just that PLanck did some contradictory things- which he himself acknowledged and repented for- eg the Manifesto of the 93 - that makes people think he supported science in society. On the contrary, he actually feared science in the hands of militarists and dictators, though he acknowledged democtratic use of science, which I guess is in opposition to Einstein.
Apart from that, I guess you could talk about his support of the war and remaining in Germany after the rise of the Nazi Party as demonstrating his belief that science ought to be used for the good of society, or you could say that that view was taken by Einstein as a humanist.
On the other hand, you could say that the differing actions of the two scientists - one fleeing abroad, the other remaining, curbed in terms of work - was due to Planck's inability to understand what the rise of the Nazi Party actually meant in a militaristic sense.
There's a lot of ways you can go on the matter. I'd probably take the route that takes Planck as believing in an integrated science with social and political influences (hence explaining his decisions in life), though this is wrong, and opposing this to Einstein's strong belief against this.
All in all, another crappy dotpoint from BOS
