That they (WSJ) published Erdogan's piece is (to me) perplexing, but for completely different reasons.
This one on qz.com seems, at least to me, nothing different from the several "puff" articles we have read in the last few years about the digital "revolution" in Estonia (and e-residency, etc.), but till now they were all or almost all by either enthusiasts/futurists/thintankers or by people directly or indirectly involved in the program at a much lower level than the President.
Personally I always had the feeling that these pieces are not entirely unlike the good ol' gnome business plan:
1) get digital in Estonia (id, residency, etc.)
2) ?
3) profit
No doubts that there may be a number of non-Estonians that may benefit from the one or the other provisions of the program, but all in all they should be a niche of "digital nomads" and/or "digital only" very small firms.
