Has the series The Witcher been taken out of Netflix before? I can't find anything about it on the net and I'm quite sure, but my brother's homo says that Netflix Originals will never be taken out.
Logically your brother is right too
On the one hand, I ask you to pay attention to the choice of words.
If your brother is gay, that's okay, but doesn't matter here.
But to come to the point: he is right. Why should Netflix take its own productions out of its range?
