Foma don't rebrand film.
They manufacture film at their own factories, at least since the 1920s, and they respond to quality issues rather well these days. The last I heard of a manufacturing problem was with Foma 200 in 120 format, which they then withdrew until they had it fixed, and this was at least two years ago.
Apart from not liking the grain of Fomapan 400, what other evidence do you have of their being "really shady at times" ?
My foma 400 120 negatives all have problems. Not only the red sensitivity issue (which is really a problem) but also, the negatives show unevenness in many areas.
What I am describing is well documented on the web. A quick search on Apug will reveal a lot of infos and rants from many users. Many serious rants. If you are really curious about it and not just looking to argue, apug has a lot of good infos on this.
As I said, I love foma 100 and 200. 400, in 120 at least, is a skip.
