I've said it before it's all down to pride, no-one wants to admit they are wrong.
It's simple psychology. Let me show it with cars, type A, and M.
Customer one and Customer two are used to be friends, had the same kind of car before. Now they devoted themselves to two different models from different vendors.
Practically, both will have four wheels, headlights, etc. The two has the same engine and transmission system even
Both Car A and Car B is out on the street. You got the wheels, the engine, the transmission. Yet for Car A the driving wheel, the seats are still in development, while for Car B you regularly check back to the Service to receive the round driving wheel instead of the initial square like, to get the new seat covers, window glasses instead of the tinfoil you had.
Not only customer one and two will never admit that not everything is perfect (as the cars are much faster than their previous cars), the vendors will make everything to stop the other from happening.
Vendor A will endlessly repeat it will be ready in two weeks, stopping those hesitating going for car M, and keeping them in an endless waiting cycle, which one day will come to an end.
Meanwhile, Vendor M will endlessly repeat that car A will never be completed, making those hesitating to be more uncertain, maybe falling for car M.
Maybe I could add, that both Customer one and two had Car A before, just some other firm purchased the factory, at first promising to abandon cars and manufacturing rollerblades instead, but things like that are biased and may ruin the picture :-)
Feel free to add corrections :-)
