I would argue that Microsoft is the ship of Theseus. Yes, they're being replaced bit by bit, but overall, it's the same ship of fools -- and finding it very difficult to change course.

Get over it: Microsoft is a Linux and open source company these days
Forgot your ThinkPad password? Get new hardware

I should have mentioned in my post as former TP support
I should have mentioned, but I thought it went without saying, that the data was toast even if the system board was replaced, another benefit of the tiered password setting. If the system board were replaced, the hard drive would as well, but the most expensive part of the machine, the LCD panel and housing (even a barely above monochrome DSTN display was expensive) could still be used. This replacing the system board and hard drive on a laptop was the solution to a lost supervisor password, which was still a cheaper solution than replacing a whole machine. Thus a forgetful customer spent $3000-$4000 instead of $9000 for a full machine replacement. The data was never compromised because it could not be accessed again. Seems pretty secure to me.
