Hi Jens
ouch....
I just took a quick look at a "professional" editor and see that their prices start at about 10 times as much as CC costs... so I took them out of the picture right away on the assumption that they have endless resources of all kinds to develop the kind of software they produce.
Then rightly or wrongly, I assume that a lot of the free editors you mention are those being developed under the Open Source umbrella. Yet again, precisely because of the whole OS mission, I believe they have many human resources available to develop their software which is almost always released as a work in progress and to be used "as is".
From my experience in here, much of the CC software develops in respect of currect and forthcoming standards - and also - and here is the good part - as a result of a great deal of feedback from CC users in here.
Let's not be too hasty in condemning them and certainly calling them "ignorant" seems way out of line for the context of your post. I just hope with time you will see just how much good work they do, and if not, that you find the perfect software to fit your needs.
