I pay for tools, even though I'm kinda broke and would prefer to save a few hundred a year - my IDE delivers a lot of value and the support is excellent (thanks Jetbrains). I installed Kite briefly but it seemed so resource hungry I switched it off soon after without ever really trying to use it. That's not a judgement on Kite, I just didn't have the time or resources to spend at the time I encountered it.

I'm sorry it hasn't worked out for them, but they get my respect for this unusually frank self-assessment, real humility, and following through on the fine words with the actions of sharing their tools they built. They achieved a lot and I hope their future endeavors are wildly successful.
