Emad had the genius idea of essentially paying for the branding rights to an AI model. This was viewed as insane in the pre-ChatGPT era, and only paid off massively in retrospect.
Also all those 'controversies' were mostly the result of an aggrieved co-founder/investor who decided to sell their shares before SD1.4's success. Emad may not have proven to be competent enough to run an large AI lab in the long run, but those complaints are just trivial 'controversies'.
