Hey, Rafa from PostHog here :)

We've always been open source, so I'm not sure I understand what this is about! This is linking to our `posthog-foss` repository which has been a thing for years now, it's simply the main repository without the `ee/` folder - which is not a folder we have a lot inside anyways, we've never tried hiding anything behind it intentionally.

edit: the title originally read "Posthog has been open-sourced" but it's now updated to better reflect what this is about, thanks mods!
