I am sure that there are a large number of small business in the field, anayway. It's not a "either or" proposition, either.
The article comes across as naive and idealistic. This was especially odd: "The average German—apart from those who’ve left the country and morphed into “tech bros”—isn’t particularly moved by shareholder value, especially when the Basic Law of Germany begins with “Human dignity shall be inviolable."
I agree with the proposoal to simplify and regulations but this is easier said that done because these are cultural aspects.

"A government program could provide salary grants based on experience, allowing these individuals to dedicate time to developing a digital product without compromising their quality of life or financial stability.*"
I would also think that someone who lives and work in Germany ought to be speaking German and would not require the German state to provide paperwork to start a company in English.
Lastly, regarding VAT exemption thresholds we perhaps need to look at the root cause of those exemptions and calls for higher thresholds: VAT rates in Europe are ridiculously high and that is in turn caused by the size of the state.
