So, my take: there are a lot of really powerful people who bought into the IPO, and so far there's been no "pop" to allow them to make a big profit. Somewhat the opposite, in fact. So, it's worth their while to somehow convince analysts to pump up Lyft, so that they can somehow push it above the IPO price.
I have, of course, no proof whatsoever. But it looks awfully suggestive.
