AI is becoming the new search. There are efforts to do "SEO" directed at LLMs so that your results factor into responses. This is a potential financial win and thus companies may choose to pursue it. Prior to the existence of a perceived financial benefit, this type of activity (semantic and accessible web) was viewed as a cost and thus sometimes done begrudgingly only to satisfy legal requirements. I'm not saying that those ideals are without merit only that getting companies to address accessibility has typically required legislative support and that is just the unfortunate reality.
