Senseless marketing decisions

Products emerge and vanish from the market.
Some disappear for the better, some products stay and become a regular offering.
But some are well resonanced and even though they pass away. The reason is never known why.
Some produtcs also suffer from over-optimization.
The manufacturers think it's good when they keep reworking and improving their wares - but sometimes they overshoot the main goal and disimprove their product.
The main nuisance about it is: They don't take it back. They stay the course they have chosen and constantly ignore the requests of the customers for reverse of the decision.
It's like they don't want your money. They can survive on their own. Or they took the plan to wait until everyone forgets.
Sometimes they also couple with offering no alternative or the abuse of knowing there's no other product on the market to replace the revised one.
At all events they want your money, but seem to be unwilling to do something for that.
It's all about "you eat what I produce" and not "I'll see what you need and get rich of that".
