The Germania service did not receive funding. The Germanwings was not funded either so there have, so far, been no failures on startup routes which in itself is an impressive statistic.
The fact that GLA has not seen many new routes is probably an indication that it was well served by the current route structure and scheduled services. The "criticism" is only from local Glasgow politicians and some GLA spotters, neither of whom have any logical case.
The new funding is encouraging airlines to start up routes which are desired but may take a little time to become profitable. Exactly what Scotland has needed for years.
