So... the idea would be I'd design, engineer and manufacture a (presumably hardware) product at great expense that's essentially 'locked-in' to a single proprietary network that could a) spontaneously cease to exist due to insolvency or such, b) increase my access costs arbitrarily or through acquisition or c) become detrimentally unreliable through poor scaling or other disruption, and I would have absolutely no recourse or ability to transfer my products over to another method of communication without initially building in such a 'fallback' (in anticipation of these potential pitfalls) at even greater expense? No thanks. Great on paper, but bad in practice, no?
