Tor Hostile
Try browsing a Cloudflare-backed site via Tor and you'll be presented with a Capcha and a "copy this crap into the box below". I've found that nine times out of ten, doing so with the utmost care and attention, it fails to convince the server than I am indeed a human. Whatever it needs to succeed is apparently not provided by the Tor network plus a locked-down browser.
I'm sure none of that will have any bearing on investment or indeed IPOs. However, the proliferation of Cloudflare isn't going to be a good thing for the privacy aware folks of the world.
