Actually, in the case of NSW, they were kicking and screaming to the extent that they blocked investigators phones from using their service. They also ran a massive PR campaign along the nanny state lines, as well as emphasising they were the young upstart pushing back against bullying and poor serving taxi companies (who certainly had their own issues), such that they got public support at the time, which got the government to change the legislation in their favour.
It was all too hard to actually enforce the laws they were breaking against them, so they got the law changed.
I think in other countries, they got less public support - or likely the taxi operations weren't as bad as here, so the public didn't see as much benefit from switching to them. As a result, they haven't been as successful in their PR campaign to be accepted by the law in other countries as here.
