Please don't give your users a nickname like "tanglers", groups come up with their own nicknames. It's not as infuriating as when New Relic started calling everyone "Data Nerd", which is actually offensive to me and weirdly aggressive for a corporate product.
Companies buy cloud services because they want to reduce in-house server management and operations, for them it's a trade-off with hiring the right people. But you are right, when you can find the right people doing it yourself can be a lot cheaper.
Around 2010 I met a friend at a bar in San Francisco and within 10 minutes we were approached by someone with a chocolate bar startup. It may have been vaguely associated with developers or maybe I'm misremembering. We got a free sample and I explained I didn't live in the US and I also wasn't an investor. They left and moved on to the next group of people at the bar.
This has always stuck to me as an example of the pinnacle of collective investment delusion that seems to exist in certain circles. They idea that you can shape the world to your product instead of improving the world with your product. You just have to try hard enough.
Fuzzy automated reviews should always run in an interactive loop with a developer on their workstation and contain enough context to quickly assess if they are valid or not.
When developers create a PR, they already feel they are "done", and they have likely already shifted their focus on another task. False positive are horrible at this point, especially when they keep changing with each push of commits.
I have also seen situations where sales opted into Microsoft early on. When they grew in relation to engineering forced the rest of the company to standardize to Microsoft products so they could get better rates and “save money”.
