I think its more of a "lol Facebook" than actual Facebook having a bad reputation. They do have a lot of money to hire talented engineers, it maybe that this solution is poor in the edge case the other post was talking about, but it may also be possible their solution is poor for Facebook. Facebook also contributes A LOT to open source projects and you can see their employee email domain all over open source projects.

I could also probably speculate their thinking along the lines of backdoors or something. But Facebook does have a good reputation with open source projects, so I wouldn't be too worried about that. (As in no more worried than some other random project)
