I am ware Tailnet Lock is available on only Free and Enterprise plans. Baffling this is to me because it is not available on the Premium plan or even the Starter plan. My logic is it shall be available only on the Premium plan and the Enterprise plan if not all plans because business entities which require such security [not that personal users do not] will pay for such access. The fact that most business entities likely pay for Premium rather than Starter or stay on Free revokes access to this staple of security. Someone explain the logic and rationale to me for this is incredibly perplexing from a logical and economical perspective. Worst case scenario make it available for every plan, not only for they whom pay none or pay customised sums.
