Any company that arbitrary limit themselves will be at an disadvantage to their competitors. LAMP for example include GPL products and avoiding it can be more costly and time consuming than the alternative (hosting solutions with LAMP for example).

A great example of such competitive environment is game development where you can't let religious fear of licenses get in the way. If a license is compatible with the business model then use it, and if not then try to get the developer to give you an exception. Development time is precious in getting the product released in the right time window and in a stable state. Studios can't afford skipping GPL development tools (which would not be part of the end product) or LGPL libraries (unless constrained by aspects shared by the competition), as the risk to the company from delayed release is significant higher than the cost of having a lawyer go through a license and confirm if it will impact the model for releasing the game. As a result many AAA games are released with a huge list of free and open source libraries.

But if you are an incumbent holder in a market with very little competition, then you can have policy against licenses and do well. What would an extra month of development for iphone cost Apple as a company?
