using trademarked names as keywords?

hey everybody,

I'm very new here as a contributor. I have just started to analyse the Adobe Stock market to find inspiration and maybe even niches.

But something confused me a bit. I read this in the starting guide:

"Do not use trademarked names (ex. Porsche, iPad, Ferrari), camera specifications (ex. Nikon, 12MP), or type of content (ex. Vector, illustration) as keywords."

But I could search for something like "iPad" and then many pictures with an iPad in it appear using the keyword "ipad".

So now I'm just a bit confused wether i can use it or not. Is it just that it's not taken so seriously anymore or is it just about writing "ipad" instead of "iPad"?

Thanks for your help
