Yeah, but the next comment was:

> "Unfortunately this is not an acceptable state for us. We have many millions of users whose Youtube experience suddenly got significantly degraded, and we're not willing to leave them in that state over the holidays. Any chance you guys could simply roll back the change you guys made? If not, we're forced to ship a Firefox update that lies to you guys about the Firefox version, which really is not a good option for either of us :("

It can still be "multiple millions" and still be very low percentage numbers, when you are accessing risk you deal with percentages not absolutes.
