"The top case assembly, including the keyboard, battery, speakers, and Touch Bar, is glued together—making all those components impractical to replace separately."
I could never handle this kind of abuse.
For how long will they replace those keyboards for free?

To whatever extent it's possible for an end user to "trigger" a failure covered under the extended warranty; it's 100% Apple's fault for making it the way they did. If the keyboards could be trivially swapped (say tool less) and cheaply produced then this would be far less of an issue.
It's a bad keyboard, but it's issues are made far far worse due to the lack of a serviceable design. Hopefully this experience of shooting themselves in the foot will make them reconsider repairable hardware.
