I use kiwi browser for the extension support.

I think it is within the company’s right to revenue increasing opportunities. That said I view the slandering of the Apollo creator as the turning point. It was very poor taste and their communication around this has been horrendous. It kick started the migration to the fediverse and a critical mass has adopted it. So now there is no good reason to go back to Reddit even if they reverse their decisions. Heck, had there been a different stimulant to fediverse adoption without any missteps from Reddit, I would still have transitioned my usage to a system where the users are more in control.

Is there one that combines Lemmy and kbin communities?

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.
