It’s the other way around with my Mum.

I think they mean modern console emu.

That’s why they ignored Dolphin emu but took down Yuzu, for example.

I’m not defending them but it makes sense for companies to use open source stuff.

Amazon’s servers are ran almost entirely on Linux.

In a nutshell: the word stealing is a vague umbrella term.

Would you classify making clones/copies out of a thing and sharing them stealing?

Steal is like taking away a cupcake from your bakery.

Piracy is like analyzing the cupcake and thus revealing its recipe and I share it to everyone. (You wouldn’t lose your baked cupcakes but everyone makes clones out of them from the recipe.)
