My objection is that merely visiting a website can invoke all kinds of unexpected things happening on my computer. As a web browser user, I don’t expect it to be modifying how timers work on my system, or accessing peripherals and radios, or programming my GPU or the memory of other processes, or my location, or writing to my filesystem, or basically anything else other than what is needed to draw text and images onto a browser window.
I still don't get your objection. Changing system timer settings is required to show HD videos on a browser window in a smooth way.
Are you objecting to the fact that that's the case or that browser windows are being used to show HD videos?
