Yeah the obvious move from them imo.

Probably best for reddit just entirely kill 3rd party API access and restrict the power of mods. Arguably they should have done that anyway like Twitter did rather than just set prices high to sort of get to that outcome anyway.

You can't change the behavior without fixing the incentives, you can't fix ad-model incentives by being a user within an ad company, the users should just accept that when operating in that space and try to operate in spaces where they can actual own the platform. If you build a company on some other company's owned API you're on borrowed time the moment keeping you around no longer benefits that company.
