You could say this about all software in the world, but good luck with that... people who make money off of making things and selling things are going to keep doing so in non-open ways, because it's advantageous. And customers will keep buying them, because it's better than the alternative.

Control plane and observability are key concerns of a fintech handling billions in daily transaction volume.
We had teams building and managing our solutions. After the migrations, we had teams managing the integrations. The headcount didn't change, we just wound up paying external vendors and sequencing multiple provider moves and company wide migrations. The changes caused several outages and shifted OKRs.
My last place also rolled their own feature flag service as their business logic around users/orgs/segments didn't neatly match anything off-the-shelf. It did what it was meant to and worked fine. OTOH we used Datadog for telemetry, which was expensive but made sense since we didn't have enough headcount with the skills to support something self-hosted.
At the end of the day, you just need to make good decisions based on honest analysis of your needs, capabilities, and general context.
