I'm sure there are secure websites to do it too. This isn't it though.
The dropbox comment isn't relevant. It's a bias to say "I remember this thing was criticized in a similar way but succeeded" and map that on to "so other criticisms aren't valid".
It's far more often than things seem unlikely to succeed to critics, and then quietly fail than that things seem unlikely to succeed to critics, but then succeed. After all, almost everything ever made doesn't see widespread success.
Our brain does remember the latter cases more, and that leads to the bias.
I see it most commonly with the phrase "X started out small too" as a defence for why something small will grow to something big, when in reality that's cherry picking massively.
