Can a seller change the product description/page ?

I have long suspected this happens ( to the point where I take screenshots if I have a suspicion or doubt - particularly if the product claims to have some compatibility or capability that might not be as described).

But in this case I've been communicating with product support about a Vine product that has been malfunctioning (an automatic roller shade device) - and after many months they are claiming that their device was not made for roller shades the size I am using.

Now after >6 months I see prominently on the product page (product title) that this is true - when I don't ever remember seeing it before.

Just for my own sanity - is it possible they added this to the product title many weeks or months later?
