I am concerned the move to a subscription product may be a threat to the long-term future of Logos.
I have been a Logos customer for decades, and I have never felt this way about Logos' future before. But I doubt that the Logos subscription model will attract sufficient customers to make it practical in the long term.
I suspect the loss of those who are not willing to pay a monthly fee will limit the quality of resources that are published in the future.
