Ignoring the snark for a second. It's not because you are unfamiliar with the go toolchain that it's inherently bad, nor does it put you in a good position to give accurate criticism.

- "tea" is an explicit alias that was added to the import statement in the tutorial examples, which you did not reflect in your snippet:

    import tea "charm.land/bubbletea/v2"

- The following also just works as you expected, but directly assumed wouldn't work:

  import github.com/charmbracelet/bubbletea

The only surprise here is that the repository authors decided to change the name of the module between v1 and v2 of the package. The git branch tagged v2 contains a module named 'charm.land/bubbletea', earlier v1 branches are named 'github.com/charmbracelet/bubbletea'. That's on them for breaking convention and surprising users, the go toolchain does not factor into, this beyond supporting versioning by naming convention.
