You can call it conspiracy theory but my 2016 15" MBP's keyboard just received it's 4th top case because of the failing butterfly keyboard.. belive me, i tried to blow it with compressed air in several ways, and i don't eat over my machine... ¯\_(ツ)_/¯

The butterfly keyboard is fragile by design.

Also, it's a bit "funny" that you have to buy a new can of compressed air every month just to maintain your keyboard...
