Take on Google Analytics
GA4 isn't a worse Universal Analytics — it's a different product that solves a different problem (ML-driven attribution at scale). For 90% of small sites, that complexity is a tax with no benefit. Plausible or Fathom gives you the 5 numbers you actually look at, with a privacy story you can put on your homepage.
Take on PostHog
PostHog absorbed half the SaaS category into one platform — and the integration story actually works. The trap is treating it as 'free' because of the generous tier; for B-grade products it's, but at real product-led-growth scale the events bill becomes material. Set event budgets early.
