Not sure I agree with you, given the facts surrounding the ordeal (SOMETHING prompted Lenovo to release this BIOS update, after all).
Now the edited title ("Linux Only BIOS Update") is much more confusing, judging by everybody else's comments. The BIOS isn't actually Linux only either; Windows runs just fine on it.
Sure it does, but it allows windows users to GASP reinstall from microsoft provided media and avoid whatever crap/malware that lenovo includes.
Thus the "linux only" label.
Right, and Lenovo didn't write the title of this post, but the mods changed it to match Lenovo's though.
OH, I just realized you probably saw the post-edit title "Linux Only BIOS Update" which I agree with you IS very editorialized (it was copied and pasted from Lenovo's page that was linked by OP).
