I realise that this is unpopular. But personally while I disagree with the decision to charge (exorbitantly) for the api and appalled at the slander hurled at the dev, I think that is an business choice and one more item that I have to disagree and live with.
But I am very excited about the rise of the fediverse. I know that a company will eventually make a decision that I feel very passionately about, but I will be stuck making a difficult choice. With the fediverse, it provides the users with the opportunity to have control. This power of course often comes with various other costs (lack of a dedicated sre or moderation teams, etc). But I expect that over time this will evolve into options where paid offerings will come up that allows for higher QoS where required.
