@tannat@bookstodon I think this is the first time I hear about an author locking themselves into the Amazon ecosystem after already being wide. To me, it doesn't make any sense at this point in time when KU payouts are even lower than they already were.
I mean, there are people making good money optimising for Amazon and Amazon only. It's a strategy. But putting all your eggs in one basket is always a risk, no matter how big the basket.
