I can't speak to the cigars, but knowing a bit about how family-run businesses work and things that happen when they're sold, sometimes people are long-time employees who are promoted and/or retained long past their ability to do their job...or they're perfectly competent but are drawing 3X the competitive salary for their position. These kinds of employees are quickly cut and/or replaced by new owners who don't have any emotional investment in these people and look strictly at the business side of things. If you're underperforming or overpaid, new owners quickly mark you for the ax.
From the employee perspective, since they'd been treated so well, they are going to have a hard time finding a new job if they're incompetent or an impossible time finding one at a commensurate salary if they're just overpaid...both of which can lead to sour grapes on their part. They look at it from the angle that the business was succeeding with them in their job, so why let them go? Except they forget to factor in the new owner paid money for the business and needs to recoup that expense. If the company has easy fat to trim, that can pay for the expense more quickly than running on the lean profits the owner was happy to accept (which are likely a loss with the loan payments of the new owner).
On the flip side, the new owner may simply want the name to sell and doesn't care about the business at all. Time will tell. But disgruntled former employees' statements need to be taken with a grain of salt.
