My reading of that is as follows. Not a deliberate plot or arrogance (even though it looks like that to us poor customers), just a result of some unfortunate circumstances that, in all fairness, could have been foreseen but Jolla refused to accept the reality till the very last moment:

1. Jolla is in financial trouble, phones do not sell as quickly as they had hoped. They launch in new territories (India, Russia) but that does not help.
2. They dip their toes in the water by trying the discount code (the first wave), as a genuine temporary promotion. The intention is to continue selling at the old price afterwards.
3. The promotion is a very mild success. They sell hundreds of extra units but not thousands as they had hoped.
4. The promotion is extended with the second wave.
5. The extention is a damp squib.
6. They try again, during the show. That registers even less.
7. They give up and drop the price permanently.

No second phone on the road map. The TOHKBD campaign and associated discount code is just a coincidence and is not part of the above scenario.
