Also in CONTEXT the Softbank CEO wants to increase services, lower prices, and increase competition. The merger does increase services for the combined company if it happens. The merger may help the company keep costs the same or even decrease plan costs as they don't need as much overhead and with 75M potential customer base may force other carriers to loosen up and compete.
Right now it's a wait and see. If Softbank does what it wants to and if it coincides with what they promised. The merger is a good thing for the end user.
