Congratulations! Stripe has consistently made my life as a developer and entrepreneur significantly easier. I still remember that feeling of relief some 5-6 years ago thinking, "Yes! I don't have to use PayPal's API!"
Honestly, I think it's a good thing in general. Like you've said, being able to just do things here and cut out all of that wasted time spent connecting disparate services... I mean assuming they pull this off well, it will absolutely make things better for me personally.
That all being said, I'm not sure how the long run comes into play here? It's bad if we extrapolate a long run prediction where no one else innovates or creates something in this space. But in reality, someone's going to be annoyed by it, someone's going to start up a different solution, and whether it works or not...it'll be there. Whether it's a small startup or a big enterprise challenging - if there's market gains to be had from adding this, it'll get added.
Don't get me wrong, you're on point with a lot of things in tech. Monoculture and monopolies are becoming super "in-your-face" considering just how much control the FAANG companies have in influencing tech and the like. However, I do find it odd that a single feature release by a larger company results, more often in not, in much of HN community losing their minds over prospective world domination. (not you op, but just in general...granted similar outrage happens to small open source stuff just as much so maybe this point is moot).
As John Maynard Keynes put it, "In the long run we are all dead." But in the short run, this just seems like a super useful feature added to a super useful product that will just make things easier for all developers.
This "sounds" interesting, and I'd absolutely love to manage ci/cd in github. Can anyone point me to some clear docs or articles on its usage? The blog post and developer guide on actions reads like some hybrid of a marketing page and a plain index of terms. Most of the examples on workflows/actions documentation and the like are in HCL which is being deprecated.
