Yeah, that's fair. I think another thing is that a lot of these internal tooling projects date back 5-10 years when open source alternatives may not have been viable yet. For example, my company uses an in-house written time series database, which probably made sense at the time because when the project started, Prometheus wasn't 1.0 yet. Now it's reaching growing pains as we've scaled, and at this point it's a bit of a sunk cost fallacy to not migrate off of it. Another thing is that sometimes it's truly impossible to use one-size fits all for some tools if your company scale is large enough. I've heard from friends at Amazon that the dev experience and tools are totally different in the hardware space than it is for those working in the retail or AWS orgs.
