Say, instead of installing wi-fi and having hipsters cram stations

They did, but it proved to be too expense. And if there were all
networks represented, with no domestic roaming, it would be up to 4x
that expensive

It was only ever going to be a single installation, with the system
likely being shared by the networks. (IIRC on the T&W Metro, coverage
was initially Orange only, but the other networks got a look in after a
short while.) There's no chance on the Tube of there being 2/3/4/5
competing installations from different networks.
