If this is about GitHub Actions specifically there is quite a bit of info at https://github.blog/2019-08-08-github-actions-now-supports-c.... My takeaway is that it's about packaging up Azure Pipelines in a way that GitHub users understand and complements other features. There are more jarring ways to integrate the products.
I didn't interpret the comment that way.
BTW, I'm not saying your interpretation is "not true" or "crazy" or anything like that. I just think it is better to keep this kind of (bad faith) interpretation private. I think it is useful to remember this HN guideline "Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith." [1]
The benefit, which is not spelled out there, is that if more of us do this, there will be fewer amplifications / chain-reactions of misinterpretations. This results in a more useful discussion.
