100% this. And if you expect people to discover the software they need on their own then you need a superb software discovery experience. AFAIK Ubuntu does not have that at the moment. I read they are working on a better software center but wonder if that will be enough.
I am not convinced this will make people switch to Linux btw. That has been said about every new Windows edition. Especially in case of an ad supported free tier (as the article mentions as possibility). Then most consumers will just use that.
