The term has a long, disputed history though, and exported English can morph and grow according to local usage. I was going to post what you posted, but more than a simple Google search led me elsewhere!
Regardless of specifics or otherwise, the app name is territorialising a domain and naming convention it shouldn’t be, and seeing as the app is available on the UK App Store then it’s certainly a case of “passing off” - a “hackney carriage” certainly is “in the UK, the name hackney carriage today refers to a taxicab licensed by Transport for London, local authority (non-metropolitan district councils, unitary authorities) or the Department of the Environment depending on region of the country“ (Wikipedia).
This app has nothing to do with that licensing of taxi cabs or their history, or comply with the legal foundations of that naming convention. Just because there’s a long history and some dispute, adding to the confusion isn’t going to help, and will be grounds for a huge amount of legal problems if this app gets off the ground, and so is better nipped in the bud sooner rather than later.
They sure are. Just seems prudent to me to use a name like CompareFare or TaxiMaxi that isn’t likely to trigger the legal weight of the entire UK licensed transport industry if you ever want to expand. The app is on the UK App Store which is likely in breach of all kinds of rules and regulations and legal frameworks concerning licensed transportation right now - it’s not like it’s a cooking app or selling wilderness camping experiences… it’s a taxi app using a very specific usage for taxis in the UK which Uber etc are strictly prohibited from using.
