Some people blame the exchanges for the issue of PI lending whales, without blaming the source. Originally, any decline was blamed on PCT, and now any lending is blamed on the exchanges.
What I've mentioned is about fighting against lending whales, not against the exchanges. Are you planning to have specific exchanges directly remove that data?
Anyway, the lending feature will not be removed from PI; what is removed is the data shown to you. In the end, the retail investors will still get cut. If you don't fight against lending whales, just wait to get cut.
