I had the same conclusion after daily driving both for 2 years; until yesterday, when my water bottle opened in my backpack and soaked them.
When I got home, I ripped apart my Framework and dried each piece. I left the M1 by my heater and tried to dry it out. This morning, I put the Framework back together, and everything except the keyboard works. The M1 won't boot.
While I did pay a ridiculous amount for my Framework, the keyboard is 50$ to replace. After the M1 design had me feeling it was more premium, it ultimately failed first.
