Sounds like that'll be frustrating for users. Especially if they have to pay and it still has ads and limited features
There shouldn't be much frustration. No one is being forced to go with an ad-supported plan. If someone doesn't want ads, they can still go with an ad-free plan.
The ad-supported plan will be an option to get the same content (with ads) for less than an ad-free plan. Some will like that, others won’t but it's the subscriber's choice.
