UserAgent: Copyright is nonsense

Steps to reproduce the problem:
1. Go to any website
2. Enter fullscreen mode
3. Observe the annoying message

What is the expected behavior?
There should be an option to disable the message

What went wrong?
I realize that Chrome developers doesn't want the message to be suppressed by an easy way, because they think it may harm users by malicious websites. However, I'm a developer and I find your "Press F11 to exit full screen" message extremelly annoying and disturbing. There should be a way to disable it. No matter how hard it would be, the way must exist.

Not sure if this is going to be closed as WontFix (probably), but I will ask you, before you close this issue, to explain how to disable the message? I've already disabled Chrome's updates (I literally deleted all executable files which whose task was to update Chrome) and now I can modify any Chrome's executable binary files.

So, pleas etell me (before you close this issue), where and in which executable is the assembly procedure which causes the message? I spent more than a week analyzing Chrome's executable files and dll's, but I couldn't figure it out. My goal is to modify Chrome's exe file in order to completelly remove the message (because you obviously don't want to provide easier way to achieve it).

It would be great if someone from your team briefly explain where and in which file is the assembly code which displays the message. Once I succeed to disable it, I can help a lot of other users which asked the same questions: "how to disable the fullscreen warning in chrome". However, every answer I saw  is telling that "it is impossible, Google didn't provide a way to do so".

However, I would really really do anything in order to disable the message. So please, I know this will be closed as WontFix, but before you close it, please let someone from your team (who actually know the answer) to explain here in comments what exactly is causing the message to be displayed (which executable file/ dll file, and which section of the file?). Please don't close the question before someone from your team explain it briefly.

I need to successfully disable the message and completelly get rid of it. Because, you know, it is extremelly annoying and disturbing, I feel like a retard when I see Chrome explaining me that I need to press f11 to exit full screen. How isulting is that? It really insults developers.

So, just to remind and summarize again everything I said, please let someone from your team explain where and in which binary file is the assembly procedure which displays the warning, so I can disable it. Thank you in advance.

Please, don't close this question before someone explain it. Thanks.
P.S. Sorry for bed inglish, I'm not from usa.
