Is that allowed under GPL V3 to limit commercial use?
I think it's more subtle than that:

The project is a mix of licenses since it's a mix of components. If I had to guess, they intend source code and maybe the binaries under GPLv3 that they own, fonts under SIL Open Font, but "brushes" and "splash images" under CC_BY_NC, etc. mean they could probably constrain certain uses:
Our Paint is a painting application.

If that phrase "for individuals" means "for individuals only", then it isn't GPLv3, but some bespoke non-free license.
My speculation: it was intended to mean: use it under terms of GPLv3 (for commercial purposes or not), OR contact to negotiate different terms.
But there's a built-in assumption that no commercial entity would _want_ to use it under GPLv3 terms.
