The difference is not encryption alone. It is scope — and a third category exists where the exit node is somebody else’s computer, which nobody warns you about.
Nobody has broken the encryption. What has failed, repeatedly, is the company holding the other end of the tunnel — including several that advertised no logs at the time.
A VPN does not make you anonymous. It changes which company can see where you go, and that swap is the whole product. Everything else in the marketing follows from it.
