one could argue the same about any SaaS-heavy operation - eg, I've heard at my place of work before "why make it when we can just pay for it" - which inevitable wraps back onto a monthly sub and rising costs. I've been blocked from completing the feature-flag implementation in our own software because they'd rather outsource that, with latency and uncertainty, to posthog.
I have to concluded that a lot of people are nowhere near as smart as they think they are.
