What is the controversy with AVAX?

Could you please elaborate on the controversy surrounding AVAX? I've heard mixed opinions about it, and I'm curious to understand what the main points of contention are. Is it the technology itself that's under scrutiny? Or is it more about the market positioning and potential competition? Perhaps there are concerns about regulatory compliance or the sustainability of its ecosystem? I'd like to gain a deeper understanding of this debate and the varying perspectives on AVAX.
