Blizzard always releases Mac versions of their games simultaneously, and they're one of the most successful game companies in the world! If they're doing something in a different way from everyone else, then their way is probably right.
This isn't an example of a logical fallacy; it could be read that way if the conclusion was "their way must be right" or something like that. As it is, the heuristic is "X is successful and Y is part of X's business plan, so Y probably leads to success".
If you think their planning is no better than chance, or that Y usually only works when combined with other factors, then disagreeing with this heuristic makes sense. Otherwise, it seems like it should work most of the time.
Affirming the consequent, in general, is a good heuristic.
Within the context of the article, the bigger form of the argument can be phrased as such:
- DirectX is not cross-platform
- OpenGL is cross-platform
- Blizzard is successful
- Blizzard releases cross-platform software
- It is more successful to release cross-platform software
- It is more successful to use OpenGL than DirectX
This is bad and wrong. As a snap judgement, it is likely that releasing cross-platform software is a more successful thing to do but using that snap judgement to build bigger arguments is dangerous.
This is an example of an appeal from author...
And happy new year to everyone.
