Great advice. Everyone needs to understand this fundamental fact about software. It's all about lock-in and control (no matter the vendor). This is the primary reason I only use open source programming languages (preferably ones with ISO standards not controlled by one, or a handful of companies). I can't imagine running a business or designing a system that relies on some closed source, black box code. It's just too risky and will come back to bite you and may even ruin your endeavor.
