Let's not fool ourselves by saying we're purely profit driven. Our industry argues about code style (:
The industry is profit driven.
The point is that our industry has a lot of opinionated individuals that tend to disagree on fundamentals, implementations, designs, etc., for good reasons! That's why we have thousands of frameworks, hundreds of databases, hundreds of programming languages, etc. Not everything our industry does is profit driven, or even rational.
