You are right but also assume people care about that. Lots of time open sourcing your project is a way to collaborate with others, build a portfolio or just for fun. It’s not a statement.
I believe OpenSUSE uses something called “meta” packages that contain a bunch of other packages. For example if there’s games-meta package it will fetch a bunch of games and during update it may try to install them again. Search through installed packages and see if you have any meta ones.
