FTL speed requires infinite amount of energy in this iteration of physics, except for case when vacuum is not empty, but even in this case medium cannot move at supersonic speed of medium, while still in one piece. If far away vacuum moves at FTL speed, then there must be "sonic" barrier somewhere.
Also, lot of links are hidden in Google by DMCA requests. PR firms use it a lot to hide "bad" information about their clients. Some countries (e.g. Russia, China) bans everything that doesn't fit their propaganda. Google is useless now for many kind of politic-sensitive searches or for investigations.
I work with Yocto at my day job too. I hate it. I have 20 years of experience with Linux, and my favorite disto is Fedora. Fedora on arm is working much better than Yocto (except for DNF: 40,000 of available packages is too much for an embedded system, so at least 1GB of memory is required to run DNF).
