Seems like a bit of a misnomer to be calling them "free" or "freebies" really. They aren't "free" as if GW is doing you a big favour to their own detriment, they are just boxes with slightly lower profit margins for GW.
That may not even be the case either, as the form factor of the boxes and the higher purchase price to shelf/container space etc may actually mitigate the lower face profit vs individual sales etc.
On top of that, the boxes often seem to throw in units that are often not that great / optimal in actual game terms and would likely not be recommended / bought as a first set if people were buying these boxes individually.
So you could say it's not much of a deal at all if taking that perspective, which seems just as valid as calling them "free" models.
If you want your army so only consist of those units sold in the SC. But if the bundle was called "saver bundle" or "battleforce" I feel like most peoples opinion on "should only be buying one" would change. Also, it's not a simple thing to say that its bad for profit to allow people to collect armies more cheaply, since it's not easy to account for the benefits of further saturation / increased sales volume etc. People getting armies cheaper doesn't inherently mean less profit.
Feels a little bit like I see you chip in to be antagonistic toward people instead of actually engaging with them regarding their views. You replied again here and expanded a bit on what you were thinking but your first post was literally
Which is not only worthless but essentially inflammatory if you ask me.
Anyhow, this is the rumour thread and this is probably just going way off topic...
