The debt company is gaming the system, but it's also ammoral so we should expect this sort of gaming. And perhaps appreciate it for exposing a bug in the rules of civil society, or what should be civil society.
The question is how do citizens react to this weakness in the system being exposed? Selfish individualism says, doesn't affect me, and that just allows more corruption, classism, and distrust. It illiberalizes society. It damages everyone's ability to trust, be trusted, have predictable and fair outcomes.
Yes the courts should be respected, but not by enacting disproportionate punishment for not showing up. The court still needs to be trusted. Why should only the court system, and the debtee be permitted to set the court date and time? Why not give deference to the accused to set the date and time within a 120 day window? It is more fair. Courts serve the people. And the business serves no one.
I also agree with the ACLU's remedies for adequate notification and burden of proof of debt.
