last thought on this for the night: one of the biggest red flags to me is that the default algorithms are conspicuously closed source. that was certainly a subject of the VC funding negotiations.
"do you have room to use the algorithm as a revenue generator if you need to, yes or no" and the answer is yes.
conspicuously, as in there is no mention of this anywhere, the last trace of it in the code is from a database migration a year ago, and literally every other part of it is open source.
