Two big problems 1) NOBODY knows what IBM's definition of "sub 1nm" means 2) IBM bullshits so much more than anyone including Intel (remember the "teleportation" ads years ago) that nobody is going to waste time researching what they mean in reality
People love to hate on IBM, ask why it is relevant today, while several of their beloved FOSS projects are in some way, form or fashion, made possible with IBM's money.
That's not what I meant. IBM published some scientific papers which explain the details. If you don't have the background to understand the papers and you don't trust the marketing that still doesn't justify rhetorically flipping the table.
