That's not what the text says. Googles spokesperson is quoted as saying they're complying with the law - but well, what is Googles spokesperson supposed to say?
The whole paragraph starting with "accused of" is not about "legally being accused of breaking the law" but about the fact, that this (seemingly) legal tax structuring is under increased scrutiny. One part of that is testing if that's actually really legal because scholars can hold different opinions and it's never been tested in court, another part is changing the laws to make this actually illegal and close loopholes. This has been going on for a while in europe and it's not a problem, France or otherwise. The fact that Google did pay up in a similar UK case indicates to me that matters are not obviously and 100% legal.
