Squeenix is trying to toe a fine line here of managing backlash. If they were to add too much housing, people who already have houses would complain loudly about how people are getting houses easier than they did. If they add too little housing, they get different backlash from people who are locked out of the housing system. The issue is that they're only putting bandaids on this problem whenever the backlash goes from minor inconvenience to potential PR disaster.
