This thing Facebook did โ running an MITM on Snapchat and other competitorsโ TLS connections via their Onavo VPN โ is so deeply messed up and evil that it completely changes my perspective on what that company is willing to do to its users.
Not if they MITMed the certificate download in the first place.
@artemesia @matthew_d_green If them MITM the SSL/TLS connection, they are doing that anyway, but how would they get a valid certificate for a competitor?
Of course their own app could ignore the invalid certificates, but we don't have to use it.
