Even if there is no tie between Evergrande and Tether there is still reason for concern.

I see people getting on u/Egon_1 for his Evergrande posts. They may have a bit of a point about no definitive evidence linking them but that doesn't mean there is no reason for concern about it. First whatever commercial papers Tether may be backed by may not be Evergrande but that doesn't mean that whatever companies they hold papers in aren't invested in Evergrande. Second even if they aren't we don't know what impact Evergrande going under could have on banks. There could be a cascade effect from those banks to other companies. Higher interest rates, banks going under (maybe not it's China) . Even businesses in other countries that Tether is related to could be affected.

Of course there is one way to prevent all this guessing. Tether needs to come clean. No one should invest in Tether without knowing. Owning Tether is holding an investment in Tether. Do you invest in stocks or bonds without doing research?
