Why do some posters get offended at the question?
Just saying…
AMG have a partnership with Ben Ainslie Racing (among others) there is the
potential for a transfer of knowledge in both directions.
Ferrari are doing the same with both WEC and Haas.
RedBull have other projects (RB17).
McLaren have a lot of side-hustles(!)
Since one can presumably also bring in outside consultants, as long as their time is correctly included, this is more or less the same, legally, but using the extra size of the operation.
I guess as said above, it might be that it's relatively new for Mercedes, while others have been doing it a long time (and Williams made money from that for quite a while too). Bringing over whatever inspiration etc. that these people picked up in their non-F1-team employment, as long as it doesn't violate agreements with their other work, seems much the same from a labor-law perspective as being such an outside consultant.
Is there potential for shady stuff? Sure, and possibly intentional in some of those cases, but cross-pollination seems like a positive thing in general which might provide new perspective and ideas. It is also a good way to keep people who otherwise might have to be let go (all big three teams cannot just let people go just like that, being in EU countries), or who want to spend some of their interest and time on something else, see Newey for example, but same probably goes for Allison.
