Your stated Case A is what I meant, but my Case B was a bit different. I'm not interested in the amount of rooters that commit fraud in relation to the amount of rooters. I'm concerned with the general case of fraud from rooters amongst their entire userbase. Seems as though that is where we're having the different opinions. If 1% of users root, and 50% of those people file false claims, there is still only .5% of a userbase. Very tiny.
Just a quick example though. I don't really know VZW's customer base, but let's say for math's sake, they have 100 million customers. If 10 customers out of 100 million have false insurance claims, that isn't going to warrant a policy change that will effect everyone. If 50 million customers file false insurance claims, that WILL warrant policy change. So somewhere in between 10 customers and 50 million customers, there is a magic number where they will start to care. In business, there is a certain cost of doing business to keep customers happy, any good businessman will tell you that. You may not see direct proceeds from it, but indirect proceeds from happy customers happen and are not directly measurable. Because of this, there absolutely is a "low number" that they will not address until it becomes an issue. Chances are that low number has been steadily rising since the OG Droid debut, wasn't large enough then, and is starting to become large enough now, and that is precisely why we are seeing the backlash.
Will they go after a single person for a false claim? Absolutely. What I'm talking about is broad policy change like locking bootloaders.
So by that definition, we're saying that enough people are filing these false claims. Okay, I can stomach that, makes sense. In the Case A argument though, for enough people to be effecting their bottom line, there has to be enough people rooting in general to not be some miniscule minority they don't care about keeping happy.
I guess all I'm saying is, rooters are a minority, obviously, but technically, 49% is a minority. I think enough people root, that Moto/VZW does care about trying to keep them happy. I took issue in people saying that Moto/VZW doesn't care about them, but at the same time is losing enough money to institute broad policy change. They either care or they don't :-/. It's a difficult situation to be for manufacturers and carriers to be honest. They want to keep a decent size group of people happy while still not losing money themselves. At this particular juncture, it appears they are more concerned about losing money now, instead of losing money in the future.
It is what it is at the end of the day and I'm not trying to start anything. This is just a discussion on things that I've noticed.
