If you want to gift subscriptions to someone, you can create a free subscription coupon to give to them.
Under Marketing in the menu head to Coupons and add a coupon.
First set the Discount Amount to Percentage and the value to 100%.
When creating the coupon, set the Applies to to Subscriptions. Make sure you choose the subscription plan you want it to apply to.
Then set the Duration to Once, they'll have a free months subscription (or longer depending on the Duration of the subscription you applied the coupon to.)
Maybe it's a family member or close friend and you want to give them a permanent free subscription, you can set the Duration to Forever. Just make sure you limit the number of redemptions so it doesn't get shared beyond your intended recipients.
Lastly, this is a bit of a workaround as the person you send this coupon to will still need to signup for a subscription using their credit card. However, if you've set the Duration to Forever, they won't be charged.
