I think it’s mostly due to the the way the “ring mains” are often wired in UK to basically cheapout of copper I think . . .
The consumer unit/fusebox/gfci protects the whole ring mains wire from overheating or ground leakage - up to the socket - but that will likely be more current than any individual appliance would want to see maybe 20A or 32A or something. So it’s up to the appliance to protect itself (and its wiring from the plug) from overcurrent scearios per its own tolerances.
Yes surely fake.
But anyone using MS OneDrive for personal stuff might want to check with some privacy advice - and I doubt MS are going to recommend doing that.
If MS is giving large increases in cloud storage and bandwidth for free/very cheap one wonders whether there’s anything in it for MS. Again MS might not feel the need to say.
