No it was pointed at Asus for two good reasons
1. Asus has a history of pushing the highest voltages through their boards when left on auto in order to be the fastest boards in reviews and when the GN investigation looked into it, Asus on some boards was pumping 1.45v through the SOC, way above AMD old guidance anyway. Yes GB and others were also overvolting and past 1.3 but by a much smaller margin.
2. The way Asus dealt with it compared with the other board makers.
3. What are Asus going to do about all the 1000s of cpu;'s which may well be still alive today but for months may have had up to 1.45v put through the SOC and will have damage to cpu, not enough that the cpu has failed yet but there will be damage and may shorted its life.
1. AMD's old guidance in AGESA was 1.4v. There are videos in this very thread that show how these initial values taken by media were not indicative of what was being received at the die as well as the methodology in taking measurements being invalid. AMD has only in retrospect addressed this limit and lowered this limit to 1.3v. The correct value can be seen by monitoring AMD's SVI3 which is located inside the CPU. It can be monitored in Ryzen Master or HWINFO.
2. GN got caught up on a statement ASUS North America made because it was poorly worded and didn't quite make sense. He opted to probe them on the PR rather than ascertain whether he was measuring the voltage correctly and continued ahead, which ended up with the data being invalid. He then proceeded to make the same mistake again in claiming the SOC was still exceeding 1.3v after the UEFI update was released.
3. Nothing, as none of the CPUs will have seen that much voltage.
Nobody can be exonerated here, the situation was handled poorly by everyone involved.
