Planka deleted my logins: the SSO tax and the open-core rug-pull
Planka 2.2.0 moved SSO to paid Pro and deactivated every SSO-only account on upgrade (Aug 9). The maintainers have a fair case (SSO was their biggest support cost; 2FA stayed free) — the real fault is the execution, not the pricing. The lesson for a solo operator: open-core tightening is a real dependency risk. Pin tags, read release notes, keep a break-glass admin.
