Belle is a disaster for the E6: how to move on?

Question

Many and perhaps most who upgraded to Belle did so because the phone prompted them to perform updates. It is considered to be the responsible thing to do. As with PC's; don't skip updates, it may harm your computer or data.
There was never any warning displayed as to the impact of the upgrade. For example a reduction in available screen, reduced usefulness or widgets or reduced function of the D-pad, were never mentioned. That was negligent. A backup was made during the upgrade process - giving the false impression that the previous version could be restored. That was misleading.
Nobody could imagine, unless they were regularly checking news and details on developments at Nokia, that their E6 would emerge from the process horrendously defaced and only half functional. Many E6 users use the phone for work and don't follow trends and developments, and can't be expected to do that. Had they been properly informed, they would not have upgraded. They have the right to get back the product they originally bought and used and the assurance that this will not happen again.
Belle has a ridiculous UI for a business phone, and much reduced functionality compared to Anna. Belle is a disaster specifically for the E6 because the screen is way too small for all the unnecessary eye candy (monstrous widgets) and Belle lacks important functions that Anna had.
If anyone from Nokia reads this, please respond. Complaining customers are still customers. Complaining customers are more useful than the ones that walk away in silent anger, because you can learn from them.
As to how to move on: Getting rid of the E6 and trying to forget about it is one thing, but does anyone consider some form of legal action? After all, when you buy something that has properties A, B, and C, and 6 months later the manufacturer single-handedly decides that the product now has properties C, D and E, to all intents and purposes the product is now defective because it lacks properties A and B.
For example, if the product were a washing machine ("New sleeker user interface, you can now start it by swiping the door, and the water temperature control is gone, it is now 60 Celcius always for everything because 95% of users find that easy"), and no matter what smallprint there is in the warranty, it would be utterly unacceptable.

Answer 1

@slitchfield: on the mentioned page, it is stated that "Improvements in screen real estate, with slimmer top status bar and optional (in some apps) bottom toolbar, meaning that all phones will have a larger useful display area."
But on the E6 the bottom toolbar decreases available screen size in most apps, most noticeable in Web browser where the full view has gone. The bottom toolbar is not optional, you can't configure it yourself.
And: "Homescreen widgets will now come in up to five different sizes (1x1, 2x1, 4x1, 2x2, 4x4) and allow a greater degree of interactivity.", but on the E6 they are in only one size, always with large borders and other visual effects.
So beware of differences between phones, perhaps some aspects of Belle work differently depending on the type of device.
"Notes now brings up a white (and AMOLED-unfriendly...) editing screen.": that you can change by switching themes, "Dark Solid for Anna" does a good job. It is a shame that the lines of Notes have gone though.
When switching themes, I found you have to restart the phone, otherwise the theme doesn't get properly loaded in all apps. Stopping/starting apps is not enough. So when experimenting and loading one theme after another, you may end up with disfunctional combinations of black-on-black and white-on-white, but it may not be due to the last theme. Also you may end up with a good combination that isn't around anymore the next time you restart your phone.
