Yeah, but the new guy's gonna be cheaper than the one with experience!
I mean, think about the next quarter benefits! Stop searching for stuff like 'reliability' or 'long term'. That doesn't mean anything to the shareholders who'll jump ship the next month.
(It's definitely an hyperbole, but it does raise a good point over hyper short-termism leading to mass layoffs for 'profitability'. The sick days are just the excuse needed to part the employes that will support their hyper toxic management structures from the ones who aren't 'team players')
I feel like that's just a very loud minority among those who play games. As you've so stated, the majority of people who play these games either do not care for politics in video games, and another subset prefer it that way.
If even the greediest of companies in the video game industry keep doing that, that means they've analyzed the market and having politics in video games might have between no to a positive impact on sales.
