So you say there is real world data on this.

Do you have anything to back this up? What I am asking for is specifically does the usage of an OS other than the preinstalled one have a causal, direkt link with the user's bank account being attacked and money being stolen from it?

You go first.

Direct specific evidence to back up the criticism that these guys are not looking at data and just making up dumb rules to reduce their customer base.

You are making an authority argument. I and most others are not buying the validity of that authority having been subjected to insane (in)security (non)standards by banks elsewhere and one other sibling commentor even mentioning their work experience for banks as evidence.

It is on you to back up your claim.

In my career travels I am yet to find any professional group crow as confidently from on top of a hollow position as software developers. I think it has to do with daily operating from inside a deterministic environment, it gets projected out into human situations.
