That is the TLDR on it, but I think Zisb & Mech22 (I think that was the other person involved the OG Pandas) only went to Drop after they exhausted all other options for having the molds fixed. Basically from what I know & remember Invyr Pandas were supposed to be a super linear switch that was as smooth as possible with as tight of tolerances as possible. As we all know they feel very short of that. Although the fact that they were good tactile housings was picked up on by the community almost immediately in the form of Zandas (V1 Zealio stem with Panda housings). Which were pretty popular, but nothing like what got unleashed when the Holy Panda was discovered.
Because of all the hype around HPs, Zisb was looking to get the molds up & running again quite a while ago, but ran into many issues with that. So he finally turned to Drop since for one they own the Halo switches which are indispensable for making HPs & they had the capital + connections to get it done fairly quickly. So AFAIK it was kinda a “deal with the devil” type thing for Zisb he felt was worth it to bring HPs & Panda housings back to a decent price point. Not ideal at all, but it did work & got HPs in to the hands of many who would not have ever touched them otherwise.
Now with that accomplished I think he might be trying to seperate the Inyvr name from MD a little bit with his own products not made with MD’s help. At least that my best educated guess on the whole Invyr situation, I could be way off as I haven’t had much contact with Zisb.
