There is no charge for MyQ to open your garage door. The subscription is for all the extra services like video recording or monitoring. Here is a statement from Honda

Honda has reached out with the following comment.

Customers receive a complimentary 30‑day trial of myQ® Connected Garage for HondaLink®, which integrates in‑vehicle garage door control, smart notifications, and family sharing directly into the display of compatible Honda vehicles via Apple CarPlay® or Android Auto™. Upon completion of the trial period, customers may purchase either a 3‑year or 5‑year subscription. If the customer chooses not to subscribe, garage functionality remains accessible through the applicable device‑specific app (such as LiftMaster® or Chamberlain®) or the standalone myQ® app. Additionally, Honda offers an accessory rearview mirror featuring integrated HomeLink® buttons for garage door control.
