That article was nearly content-free. Brief review of history and then some talk about a supposed "third wave" of migration is not clearly characterized, nor actually foreseen in any detail ("certainly X would be a good place to start" - thank you captain obvious). No discussion of anything signifcat: * Are commercial corporations contribution back to FOSS software they use? * * Additional functionality and bug fixes? * * Grants/donations of money, hardware or even developer time? ... Amazon, Google, MS run mostly FOSS on their clouds, and pocket billions, but certainly don't give much back. * Does "open source components" just mean FOSS inside but closed commercial outside, or do companies transition to making FOSS? * What about hardware? Or at least, device drivers and firmware? * What about all those SaaS and PaaS platforms even the article itself mentions? Their engineering setups, and software in particular, are mostly closed. Where's that promised "wave" for them?
