They were purchasing the company by making payments to Fin on a schedule. At some point, they stopped making payments. Several months elapsed with no communication, so Fin had to sue them. Then they declared bankruptcy. Fin is out over $200,000 in money that was owed to him - the equity he built over 25 years. On the bright side, he's doing well in the solar industry.
Nobody knows what was in the Callens' hearts during all this. I don't believe it was malice. Just a perfect storm of extreme incompetence, negligence, ignorance, indifference, hubris, delusion (e.g. the career/life coaching stuff is just over the top - who talks about themselves like that??), downright stupidity, and finally panic and desperation. I do think they believed they were trying to save the business. Regardless, they hurt many people and didn't seem to care, at least not enough. They are guilty and owe a debt to society.
I am 100% with Fin.
