It was certainly a giant blunder, but like all of these issues they are Windows only, and usually only if you use the factory OS image.
Like most(?) of the HN crowd not using Apple products, I run Linux, so that kind of stuff doesn't affect me at all. I assume the remaining ones reinstall using their own installation-media too?
It doesn't excuse Lenovo's behaviour and certainly can make you question their judgement, but all in all, I'm one of those who are putting less weight on this issue than others may do.
What matters most to me, are the practical aspects: what can this product do for me? And Carbon X1 Thinkpads are among the best lightweight laptops out there.
