OK, but isn't that just a difference in semantics? (Not that semantics aren't important in marketing, mind you.) You can say that there's a 2-yr contract with an ETF based on the number of months remaining in your contract, or you can say there's no contract but you'll have an "installation balance due" based on the number of months until you reach your 2-yr anniversary.
And if they were to go that route, that would effectively mean that new customers would pay a *higher than regular* monthly price to begin with. So it wouldn't just be a matter of scrapping the reduced first-year promo pricing to entice new sign-ups, it would actually mean raising the cost the first 24 months above what you'd pay after that. Which might be fair to longtime customers who have long ago paid off their acquisition costs but it's probably not a great way to attract new subs. (But then again, I suspect the game plan going forward will be to use DTV Stream to attract new subs while just trying to hold onto DTV Sat's existing base on either service at a sufficiently profitable ARPU.)
IDK, I guess DTV Sat could be really slimy like lots of cablco's and have a fine-print "installation fee" tacked on to the advertised price, the same way caboco's do with their broadcast TV fee, which is typically in the $15-20 range these days. At least the installation fee wouldn't be permanent, only for the first 24 months. And as you say, it could be optional too if they allowed self-installs, including re-use of existing installations.
All that said, I'll be surprised if they really re-jigger the formula too much for DTV on any front -- pricing, packages, hardware. As I say, I think the plan will be to mainly advertise and build up DTV Stream while DTV continues to melt down (hopefully more slowly) toward a base of sports-loving rural dwellers.
