It all comes down to pay.
Gaming industry (that is in corporations) is simply low paid and it has consequences. When it comes to writing it means people do not have qualifications to actually write anything decent - they are either not up to the task or too inexperienced, and once they gain the experience they move to another industry. Who even stays in the underpaid gaming industry? People go into it mostly because it has easy entry, so as the first or second job it's fine, but once they get experience they leave somewhere that pays much better. It's not limited to developers, it's everybody: Writers, designers, testers, even managers.
Only losers stay in gaming industry unless they are small independent teams (and often have other jobs), but majority of people simply moves on. After all, it's an industry that pays low but requires an education, so people there are typically not complete morons, just inexperienced, and seek other opportunities when they present themselves.
