I’ve found virtually every company is going to be very straightforward when it comes to answering technical and feature related questions about their products. And if it’s something they consider proprietary information that they don’t want to share, they’ll come right out and politely say so. You might run into the occasional small boutique operation being less upfront about something than you’d like. But you’ll rarely run into that nonsense with established businesses. tl:dr - That hasn’t been my experience.
