Thank you! There are definitely platforms that intentionally gate-keep their APIs. A good example is LinkedIn, which many companies still try to force-build their own integrations with. Our goal is to allow each developer to make their own informed decision regarding the policies of the platforms that they're working with. For our hosted service, we want to prioritize use cases where the end-user truly owns the data. We can also refer to legal precedent cases where many other companies make unofficial APIs.

I don't think it really matters to them. As a provider giving access to these platforms, they're not the user (and they didn't agree to the terms). the end user did, so it's on them to decide whether they risk getting terminated or whatnot

If they have deeper pockets than the user, they're the ones who will get sued for abuse they enable.
