Netherlands, and the EU in general, are cumbersome to deal with regardless of all the "startup incentives" they've been pushing in the past few years. Compare the incorporation, maintenance and closure processes of a Delaware/Wyoming/New Mexico/Florida LLC with anything even remotely comparable in Europe (e.g. a BV/NV/SRL in the Netherlands) and you will quickly see why the US has become the world's center-stage for doing business.
For SourceHut Estonia and Romania would have probably been a better choices, as from my understanding, they are not investor-driven and do not seem to head that way, they are fully digital/remote, and they require disproportionally more infrastructure than office workers to operate.
However, when living in the EU one has to take into account various (frankly absurd) taxation laws that might ultimately prevent founders from incorporating their company in any of the neighboring countries. Hence it would be necessary to look at the details of the founder's circumstances to evaluate if incoporation in a different country would have made sense to begin with.
That said, I agree with the top rated comment [1] as for the broader topic of where to incorporate.
