Great App, Bad Subscription Model

I bought and paid for this app before it was free with optional patronage, and am disappointed that my purchase didnt even get me some credit for patronage. It seems to me, that people who previously paid for the app were not considered, before the choice to move to a subscription patronage model.
The developer hasnt responded to any of my emails or tweets about patronage and offering free updates of new features for people whove previously bought the app. All I want, for having paid for the app, is to get Dark Mode. Is that too much to ask??
I dont agree with the way software devs have been focusing on subscription models. I always choose to buy standalone apps.
Its a great podcast app, with great, unique features. But, if the developer continues to ignore their customers needs, they... And I... Will be using s different app, as soon as theres one with the same features.
