Germany is a big player (politically and financially) in the EU and the Eurozone and it's benefitial to have them on your side.

(Also such a large economy can offer better (aka larger) subsidies if they want to)

Eindhoven is also still growing: https://siliconcanals.com/news/startups/dutch-smart-photonic... Much smaller though!

It's probably good for the EU in general to have multiple silicon hubs.

Germany wouldn't have subsidised that one though - this was German money.

Eindhoven also has a recent influx of PhDs from Philips looking for a new place to work...

although imo Eindhoven isn't exactly the most... attractive place to live for many people. Dresden on the other hand seems like it's somewhat en vogue
