I'm too much of a cynic. In a different lifetime I tested aviation flight components, and I learned one thing. The decision for a company to actively issue a recall consists of the following checklist:
1) How much will it cost to recall and refurbish the defective devices?
2) Calculate how much would it cost to leave the defective devices in the wild and reimburse people on a case-by-case basis?
3) Perform the cheaper task.
A company doesn't recall JACK out of the kindness of their heart, they are in a situation where they're at risk of losing their shirts because of the batteries. They know they have to get them off the street, pronto.
It's surprising that a company like Samsung messed up so badly. Samsung phones are de facto gold standard Android devices to most average consumers, and now Android looks even more inferior to the high holy iPhone. In the words of my VERY non-tech savvy wife, "Why don't you just get the new iPhone?" I rolled my eyes so hard I pulled a muscle.
