No I am not wrong here. The manufacturer doesn't supply most of the roms like you state they do, so just because it is easy and possible doesn't mean they approve of it (most of the original roms are derived from device extractions and not the manufacturer providing them) and was the whole point of my argument, so you missed everything.
Also not all manufacturers supply the code either. This is why the droid fans had so many issues with rooting and newer no approved roms that made some of their hardware, such as keyboards, not work fully and in some cases not at all and the first 4g androids had no capability to run a vanilla rom and access the 4g radios (if what you claim is fact then this would not have been an issue, yet it was).
The argument that you are defending against was solely that the manufacturer doesn't supply or approve of downgrading. You have yet to provide even one valid claim stating the otherwise. Just because something can be done doesn't mean it is a supported option. Good day to you since you failed to provide even one proof otherwise (other than the few I provided originally) and are stuck in the hacker days. It is like arguing that the manufacturers support rooting and jail breaking because it can easily be done and the directions are out there on a third party site. I have done them and know it is easy but that doesn't mean it is supported by the manufacturer which was my whole original point, way to miss it.
At least I know, Samsung, Asus do supply official ROM on their website.
Here is Samsung Mobile official ROM download:

If you go to Asus website, they provide firmware for their tablet as well, here is firmware for TF700T

Here is all the ROM available for Nexus:

Again... All I am arguing is that regardless whether manufacture approve downgrade or not. It is entirely POSSIBLE for people do downgrade. However, on Apple's case, there is NO WAY to downgrade.
Even if most manufactures do not approve downgrading, rooting, hacking or anything. They don't go block every possible way like Apple do, that is the difference. Most manufactures do not publicly say they support downgrading, but they have no issues with you do so.
Arguing manufacture support is meaningless, in the end of the day, it is the problem of wether you can do it or not.
