Because lying is wrong even when open source projects do it.

I think it is a big stretch calling this visual effect lying.

I don’t know if it is a cultural American thing or just difference in interpretation but I had no difficulty understanding that this was a visual effect. But in my country ads don’t come with disclaimers. Do you feel like these disclaimers are truly helpful?

I don't feel that the person I responded to is lying or being intentionally deceptive.
