I'm sorry. I'm too dumb to parse this. :(

I am sorry. I was too dumb to phrase it understandibly, so the shame is on me. The sentence smelled problematic to me but after several times rereading it I concluded it is understandable. I should have gone with my guts…

Here is another try: Samsung's support walls with prewritten answers that say Linux is open and thus Linux is unsupported, and this action of Samsung is consisting with the testbed-theory.

Don't sweat it, I'm the king of less-than-comprehensible statements. :)

Anyway, I get your statement now. Maybe instead of saying "walls" you should say "stonewalls" (derived from "stonewalling")?

I think the confusion stems from your verbing of "wall".
