Oh, interesting, I thought this was coming later. I'll probably check it out at some point.

I'm a little confused about the Founder's Pack delisting though. I thought that was just additional content for the game, not something separate, so what is it, exactly? Are the people who bought it going to be refunded? Or was this some sort of shady cash grab?

I think the founder pack unlocks all the characters.

The Founder's Pack was always going to be a limited time bundle. It had been discontinued on other consoles in late April. If you bought you'll still get access to all current and future champions. Nothing shady about it.

Ah, okay, so it was just a way to unlock stuff without having to play the game a lot?
