Every security product needs to make trade-offs between confidentiality and availability. Addressing all "legitimate security (meaning confidentiality) concerns" results in the proverbial turned-off computer under a mountain with a Marine standing guard. Agilebits have chosen a trade-off which maximizes their users' availability while minimizing Agilebits' best assessment of their users' potential for unacceptable loss of confidentiality, in service of delivering the best product that they can.
Now, you may disagree with Agilebits' methods of assessing those qualities or the particular trade-off they're choosing to make here, but you can't claim "security" in the abstract to justify a change without articulating its costs and benefits in more-concrete terms.
