I wasn't implying that YC had changed, just that
I can't tell what the reasoning is anymore. The second link is an interesting thing to link, because the reason I included the last line (along the lines of "I guess it could be sold to a malware vendor or something") was more or less because I was thinking on that; I took my time to think, and couldn't find many optimistic things.
My only other guess outside of the one listed is that it could be sold to Facebook or twitter after getting a large audience, because it aligns with historical acquisitions somewhat.
I'd be happy to be shown wrong in a year (I'd literally take anything over what I imagine is going to happen to it), but presently I'm mostly just confused.
Responding to the edits I only noticed after responding:
"Don't be discouraged if what you produce initially is something other people dismiss as a toy. In fact, that's a good sign."
I wasn't trying to discourage the people making the extension! I was mostly seeing if I could get any spare guesses as to what YC's mindset was when thinking about this.
Regarding whether what it's combating is a big deal:
Certainly, but I'm not sure if the solution to all of those is...a new big tech company, to put questions of profitability aside. It seems partially like bait to be acquired by a social media company, or Nielsen (which is a literal malware company at this point, they pay users to MITM their connections; a way to get the same data without paying seems like something they'd love).
