Charge per presentation
This $7/mo plan is nonsense for those who don't do a presentation every month.
Why not charge $7 to unlock premium features on a specific presentation, or some other value?
Thanks for the feedback but we don’t currently have any plans for changing our pricing model.
The pricing model is likely to be adjusted over time, but that decision will be made internally.

Would it not be enough to start a subscription and then downgrade right away - but let them keep the card details. This way you have pro for one month. Of course slid.es would have to let you keep the presentation in pro format after time runs out.
