What makes IT infrastructures special compared to anything else that we should avoid political matters?
For me they are critical and omnipresent. So crucial, in fact, that they are somewhat at the center of political matters nowadays. They are probably a core part of many policies.
And I believe the way they are done cannot avoid politics.
Trying hard to project into myself into your perspective, I'm trying to compare them to roads, which are infrastructure too. You could say they should be neutral and let anybody use them without discrimination...
... but they are not neutral. The way they are built consume more or less energy, have various environmental implications, they more or less encourage usage of cars or trains or planes depending on how the network is organized, how they are maintained, which facilities are nearby roads… And many roads are not very usable without cars so they actually discriminate.
I believe the same kind of things apply to IT infrastructure. Most choices will have political implications and therefore you'd actually be careful when designing them.
Now, regardless of whether IT infrastructure can be kept neutral (which I don't think is possible), I actually think that we should not and that we'd better work hard to leverage, and design them the best we can to limit our environmental footprint (for instance).
