Personally, I agree. I have no problem with paywalls, and actually subscribe to one paid site and wouldn't mind subscribing to more. But it can be pretty irritating for an aggregator. I go to paid sites individually, not from an aggregator.
Not really interested in naming and shaming because the lead dev trolls the internet to find people that don't like the framework it so he can publicly mock them.
As for PyPika, I wouldn't be fond of that, but that at least has an ability to get the raw SQL being built. There's no such option in my framework (and I've looked for hours combing the source code trying to find it), so debugging why the data coming out is wrong is kind of a nightmare (especially since the documentation is incoherent).
As a dev, I have to use a query builder. It's frustrating because it's ten times more complicated than SQL and slower to execute, with basically zero advantages.
