1. Incorrect, since many bugs only happen under certain circumstances. Those that do are typically caught by Q, even if QA is bad. It's the ones that don't happen to everyone that can be missed by QA and therefore make it into the released game.Plot-Twist 01: Every bug ( whether it's just a minor or a mid or a major one ) affects ( or will affect ) every player since every player plays most likely the same ( newest ) version of Stellaris. Plot-Twist 02: The situation doesn't get better with Paradox "tradition" to accumulate bugs like badges. Plot-Twist 03: "It's hard to fix" is an ... explanation ... that customers and most laws ( in regards to customers ) don't accept anyways.
Plot-Twist 04: Paradox is past the point to "survive" ( profit = ( at least ) 0 ), but how much profit. Plot-Twist 05: "Shame" on customers that live capitalistic core-values on their own as if ( plot-twist 06 ) capitalistic core-values aren't just pureley reserved for companies.
2. And your point is?
3. As for customers, as long as only a minority encounters a specific bug, why should paradox care. As for laws, as long as the game works as advertised, there's nothing to base a legal case on. Any bug making the 'works' part merely more difficult isn't sufficient.
4. Paradox is not a non-profit organisation. Fixing bugs requires an investment. No company in the world makes investments with no chance of a return in some form, even if it's only for reputation. And reputation is only meaningful if your efforts are visible to a significant number of people (or a number of significant people ). Fixing bugs that are only visible to a few people is therefore not a sensible investment of money and resources.
5./6. No idea what you mean. Me, I eat to survive. And so do companies. I've never heard that producing hot air has a nourishing effect...
