[...]and they must IMMEDIATELY restore it – and they face full legal responsibility of any losses you incur if they do not!
Sadly. that's not the case.
And if that doesn't help, there's certainly something in youtube's terms and conditions that they can host or not host anything they want at any time they want for any or no reason, and that it is your own fault to rely on their services. I'd expect their liability to be limited to what you pay them for hosting your content, some very low symbolic amount or just plain nothing, whichever they can get away with in the relevant jurisdiction.
There's about 1kW of photons centered around the visual spectrum hitting every square meter of the moon. It's very difficult to detect a measly laser among all that noise. In the radio spectrum, it's much easier to get a few kW of transmit power, and there's not all that much natural noise, so the signal is much easier to detect.
If you want to know how hard it is to bounce a laser off the moon, read up on the Apollo Retroreflectors, where "Even under good atmospheric viewing conditions, only one photon is received every few seconds".
My experience from 1996 is quite the oppiosite. I bought a S3 964 based card after those were on the market for more than a year, and I had to find that XF86 was running in false-color so to say. S3 sent me the printed programming for free by international airmail essentially no questions asked.
It turned out that the problem was the way the external IBM RAMDAC was wired to the S3 chip - easily fixed with a 2 or so lines patch, Back in those days manufacturers of graphics cards dodn't just implement a reference design, but had lots of choices which components to connect in which way, which didn't really make things easier for open source developers without access to every hardware variant out there.That essentially ended with the S3 Trio/Virge and the ATI and NVida 3d cards.
