I don't think there is anything wrong with paying for what you consider to be value. I pay for Nebula for similar reasons. Similarly, I don't have a problem with free services including modest ads to cover their costs and even make a profit.
I do have a problem with ads that have gotten so aggressive that the free experience becomes unusable. For many providers, I feel like they have lured in content creators by promising free access and then changed the bargain after the fact by making the free tier intolerable.
It will be near the top of the list of fonts since it begins with "A". I think that was what they were getting at.
