I do not think that Easyjet will disappear. But I do think that they have achieved the unthinkable and managed to annoy more people than Ryanair. O'Leary may not be to everyone's taste but at least his communication on the website was dignified. Easyjet have not thought it necessary to communicate to their passengers other than through flight cancellation messages only offering the option of rebooking onto a load of flights which in all probability will not be operating, with the proviso you can only change once for free!
The future of the company depends on the goodwill of various stakeholders, the government who are obviously irritated by the dividend to shareholders, the staff where the crew meal issue seems a case of very poor timing and the frequent customers like myself who are wondering about the lack of communication. It is not true by the way that no airlines are refunding tickets. I will make a point of using those that do in future.
