For non German speakers, the taxi unions sued to restrict either zone, or number of vehicles back in April and won.
This article is about that being overturned by a higher court and allowing MOIA to extend the fleet from 200 to 1000 vehicles.
There's a paragraph in the article dedicated to "massive criticism from the taxi drivers" where the chairman of the Hamburg Taxi association says:
> ...The aim of the VW subsidiary Moia is to replace as much of today's public transport by private offers...
That implies that he thinks Taxis are a public transport, but of course, they aren't. Taxis have no affiliation with the city to my knowledge, save for some regulation.
Hamburg has an excellent multi-line metro network carrying millions of passengers per day and taxis are prohibitively expensive here. A taxi from my place to the airport, a < 10 minute drive is easily over 30 EUR, with MOIA (if serviced) it would be something like 85% cheaper.
