Analytics when used as a go package

[kke]

One way to disable analytics would be to set segment.WriteKey to "" before reusing phases, but forgetting to do so would make the 3rd party app send k0sctl telemetry.

The best fix is probably to move the segment write key into the initAnalytics function used by cli commands. Or to remove analytics, nobody looks at them.

I think @alessiodionisi 's terraform provider for example is secretly sending k0sctl analytics to segment.

hmm, what if we "inject" the key via buildflags only on the official k0sctl builds?

Then it's not there for homebrew (unless it's added into the brew-formula), that's why it was hardcoded. A similar problem as for k0sctl version in #479

right 🤔
