If you want to move to Europe (which I think was part of the idea of the article), it may indeed make sense to consider where to move. Germany (and one of its startup hubs, like Berlin or Hamburg) is probably not the worst place to be for various reasons, but I've also heard good things about e.g. Estonia.

I don't have backup readily available but I think your statement about the taxes is just plain wrong. Generally I think income is taxed where it is produced and Europe has (no)double-taxation treaties with pretty much any country. Personally I'd still avoid the extra complexity for a startup :-)
