I&#x27;m very sad to see this announcement. I&#x27;ve been a big fan of persona since I first learned about it three years ago, and for a few months I tilted at windmills by writing to services I used, and asking them why they didn&#x27;t support persona login.<p>After writing about four of these, though, I had a small epiphany; this is a ludicrously uphill battle, because Facebook and Google don&#x27;t just make it easy to use their login because they&#x27;re nice; the information that they gather from these logins is worth good money to them, and so of course facebook+google login is the most frictionless and butter-easy way to implement login.<p>Sigh.<p>Okay, I know this was totally obvious to everyone but me, but it does make me sad, and I can start to see the outlines of an internet that I&#x27;m somewhat less excited about than the one we have now.<p>I&#x27;ll miss you, persona. Mozilla, keep up the good fight!
