To whoever the downvoter was: no, seriously. For instance in the first few paragraphs:

* emoji were invented by NTT DoCoMo, not Softbank

* even if that had been right Softbank's copyrighting of their emoji representations has no bearing on NTT and KDDI/au using completely different implementations (and I do mean completely, KDDI/au essentially use <img> tags)

* lack of cooperation is endemic to japanese markets (especially telecoms) and has nothing to do with "ganging up"

* if NTT and au/KDDI wanted to gang up on Softbank you'd think they'd share the same emoji

* you didn't have to run "adware apps" to unlock the emoji keyboard (there were numerous ways to do so from dedicated — and usually quickly nuked – apps to apps "easter eggs" to jailbreak to phone backup edit/restore)

That's barely the first third.
