@SuperDicq @waifu It seems I can tell which software is proprietary by feel now before I take a look at the license and it turns out it's proprietary and it seems such skill even works on anime.

The thing that improves or decreases the quality of the anime is the portrayal of the proprietary software.

Portraying proprietary software as a good thing decreases the quality.

But it can increase the quality - Shimoneta for example contains lots of proprietary software, but it does a very good job of portraying the consequences of proprietary software.
