You know, it is not beyond the realm of possibility. Cat brought that up before, but think of the facts. The redesigned characters are nothing like the originals. Black boxes, plenty of excuses with very little progress. Their online presence definitely seems more like an emulation than the real thing.
No other well known maker of these games (Dr PinkCake, UnderGrad Steve, RJ Rhodes, Ocean, etc.) has changed and they have kept their products consistent and/or improved. Yet only Braindrop seems completely different. Making up mental health issues (even stress can be considered a mental health issue) to mask the fact you are not really BD and then bringing in a "Mackenzie". Is Mackenzie the first name of Braindrop's new online presence, or just a name they like? He did say Mackenzie was taking over his PR while he works on the game.
The new Braindrop, if there is indeed a new one, likes to rake in the money, but comes out with a much inferior story, the character models have changed, black boxes suddenly appeared. Now, the new characters seem to have big butts and boobs and the redesigns look nothing like the originals (definitely missing details the old ones have, like beauty marks and such). It went from professional looking to amateur hour, not to mention the story has completely tanked compared to the original material.
To answer, it is not impossible and evidence points towards it. Most conspiracy theories are easy to shrug off, but in this case it could very well be the case! The problem is, it is not likely going to be an easy thing to discover.
