I think that is somewhat naive. The general approach of big tech has been: let's just break the rules until we get a slap on the wrist. It's not like privacy authorities are going to charge them with 4% of the annual turnover the first time. Besides that, they probably have bigger fish to fry than some program that is used by a tiny subset of the general population.
As someone working in big tech, this is very far from truth. In any questionable case there are endless legal and privacy reviews that catch 99% of possible transgressions. What you see is the 1% that slipped through this process.

That's exactly the reason why MS would be on the safe side and not break any laws in this case. They could be a bit more daring if it benefitted them, but in this case there's literally no benefit except improving the software that they are giving out for free.
