If anything will ever kill established "Enterprise Open Source" or Open Core business models, it's because of cloud service consumers and cloud platform customers that prefer the seamless and often convenient integration of FOSS services and technologies their preferred cloud platform (be it Azure, AWS, GCP, or whatever other player that reaches a sufficient size to be able to) provides.

That happens to the direct financial detriment of the companies that actually created these free tools, while (perhaps naively) hoping to be able to sell services based on them to enterprise customers themselves. And it's going to be a real pity and for the FOSS community when it happens.

Software may be eating the world, but managed software platforms are eating (free) software.
