Let's say I believe somewhat in Karma, at least in that you can try to justify something as much as you want and as long as you want but only YOU truly know if regardless of legalities if what you did was morally and ethically correct.

I personally understand TH's position and every DIY's position out there and would rather give them a chance to make things right or give them a chance to get that refund from Yifi, provide a product, or do whatever they have to do before giving them a chargeback. This is correct morally and ethically based on the type of product I purchased from them at least for me. They only need 1-2 months maximum to get back to customers with what they were able to accomplish in this area, if there is no product, there is no partial refund and a product, there isn't a full refund, then yes action can be taken.

If you feel self justified to try and kill a company that literally came into this space trying to help miners by asking for a mass exodus of refunds then go ahead no one is stopping you. Just understand you have to live with that fact that you value greed over integrity.

There's really not much else to say, there's no argument to be had on this discussion. Obviously there's a simple difference in belief on this matter regardless of Law.
