Earlier quoted context omitted.
you forgot they are running a multi trillion dollar industry on free-as-in-beer software. I doubt they would pay $5 per user. or even a year flat fee. and since they will not pay, you will have to run it on ads. And supporting online/mobile offerings (that do not have their requirement of local client/local logs) will always give you more money. it is a lose/lose situation.
> you forgot they are running a multi trillion dollar industry on free-as-in-beer software. Isn't that the basis of enterprise linux?
Not to mention that any enterprise Linux user worth their salt has an expensive support contract with a major vendor (such as Red Hat). Either that, or they're confident that they have the in-house resources to support it. No enterprise user considers Linux to be "free as in beer", by any stretch of the imagination; rather, they're using it because it's the right tool for the job.
