I don't think it was ever a big question. In fact, I don't think anyone ever asked about how clocks work on Mars.

I don't know what the price difference is between a 5GbE and a 10GbE part, but it seems that putting a 10GbE port in might be a bit more 'standard'.

Inflation is only a single factor for a price increase, however there's other factor's that also counter act where they made up the money - DLC, Season Passes. In addition to cost of living up while wages stagnant, etc.

Yes. There was a post about it just the other day...

Thank you, Captain Obvious!
