they can only work around flawed implementations of blocking third-party cookies (i.e. generating exceptions on the fly)

you do not support sites by allowing ads, without buying the products.
A ad costs the advertiser money: money for the space at the homepage (the money you want the homepage owner to have) and hosting cost (traffic, server rent). If the advertiser shows you the ad, its costly for him. If you buy something, its profitable. But if you do not buy something, the sum is negative, so he will lower the pay for the homepage owner in the long run. So only unblock ads, if you plan buying stuff from them.
Most intelligent people do not buy because of ads, so its pointless to unblock them.

you're implying, there would be more murder, if it were legal.
No, it would not. But it needs to be illegal, so you can (legally) punish the murderer. You cannot do this, while its still legal.

the final hack is a camera in front of the monitor. But the quality will be lower and/or the methods will be more complicated. So you can at least limit everything, which happens in software. While still using opensource software.

progress measurement can be (and the user wants it to be) a percentage of the total time. and in this sense, an option might be to make the progressbar longer, when the estimated total time grows (because the progress grows at a slower rate than expected).

the total bar should get longer. sorry, if my posting was unclear to you.

you're not understanding my postings. GPG is opensource, your private key is not. A program reading a encrypted video-stream and forwarding it via a trusted path to the graphics card can be opensource, the key inside the tpm/graphics card/monitor cannot. so trusted computing enables opensource DRM, while the current situation requires closed source to implement a DRM-System.

Two totally different things. No need to track me, to present ads to me.

its showing you: hey, IE is not hanging.

they should become longer instead of moving backwards.

yeah, it would have flaws. But assume its there, then it could be used with opensource software as controller. No need for closed source to provide restricted access.

of course, you can try to rip the display signal short before the tft-panel. But this is much harder to rip than just saving a movie file. you will also need to re-encode it and have some quality loss. It will certainly make ripping much harder.

no, its not decoded in the monitor, but by some trusted piece of software, which is certified just to decode and forward, and not to save it to the disk.
And there are ways to protect against replay-attacks.
