On one hand, yes, in theory k8s is pretty extensible. In practice, though, you always end up being forced to do things you do not want or need to do, or being prevented from doing things you want to do, because of vendor specifics. Sometimes that is an acceptable tradeoff, sometimes not.
Plus, it is always good to take a step back and appreciate that monoculture is a bad thing in computing. We always need more different approaches, viewpoints, solutions to the same problems. Should everyone roll their own? Of course not - that's why I mentioned having sufficient manpower and expertise to do that.
We should be applauding having more choices and cheering, not scolding those who strive to provide them.
As for your last paragraph, I completely agree, we need to share the knowledge and cooperate. But expecting corporations to "potentiate & enrich" us is rather naive. They will play nice only as long as they need to, and the minute their financial incentives do not align with sharing, they will do their best to pull the rug from underneath everybody else. Even their sharing phase is only to build levers to use in the future. We've seen it over and over and over for the past several decades, with Oracle, SCO, Microsoft, Apple, Google, ... heck, I could pretty much list all big companies.
