In Drupal 8.x hiding the subject line is a quick task.
In the admin area of your site go to structure > comment types > {comment type} > manage form display and the URL will be like https://domain.com/admin/structure/comment/manage/{comment}/form-display.

Action
Drag the subject to the disabled area and save.
