On the contrary, I thought that tether is the one fueling bitcoin's massive run?

So it they continue to mint then obviously bitcoin can reach $100k. However, with or without tether, I think bitcoin could still reach $100k. Maybe not this year, but eventually the price has been growing exponentially. We have seen it reached $64k, so that's an obvious sign that we have a lot of leg room to make $100k in the next 2 years.
