If Kitely can afford to keep the regions active for people, more power to them. Eventually, the costs might get too high and they might scale back. Or Amazon might keep dropping its prices and Kitely will offer even more free land. Who knows.
Instead of complaining about it, other grids should look at ways to be more competitive. For example, Kitely is pretty weak when it comes to in-world community, most relying on in-world volunteers to carry the ball. They still don't have an events calendar on their website (you have to really hunt to find out what's going on in the grid.) Other grids should be doing more to promote their live music venues, their parties, their building classes -- all the good stuff that they do.
