And you know what the linux answer is? The cost to implement and maintain linux is high no matter which vendor you use, so there is no vendor lock-in. You can pay top dollar to the vendor of your choice.
In other words if you truly think Linux avoids the issues of vendor lock-in you're smoking crack.
When you take a moment to think about this, some day, and realize what vendor lock-in means, you'll understand why you've failed so miserably in this discussion.
You're the one arguing "oranges" when we're talking about "apples". You don't even understand what we're saying.
Your 'situational awareness' is near zero. You do not hold the beach -- I repeat, you do not hold the beach.
