I’d say from a grantee pov, which is I guess a large fraction of the highly-engaged EA community (eg commenters on a post like this), Dustin/GV/OP have mostly appeared as an aggregate blob—“where the money comes from”. And I’ve heard so much frustration & disappointment about OP over the years! (Along with a lot of praise of course.) That said, I get the spirit of your comment, I wouldn’t want to overstate how negative people are about Dustin or OP.
And for the record I’ve spent considerable energy criticizing OP myself, though not quite so far as “frustration” or “disappointment”.
Do you see any risk that the marketing increased the number of applicants, but also on average lowered their level of interest or how much they had to contribute? I’ve had some experiences like that before when promoting events very widely. (Though I’ve also had the opposite experience, where casting a wide net brings in amazing people you’d never have reached otherwise.)
I’m sure it depends on the type of marketing used, and in general I agree marketing is an important tool in the toolkit!
