> a strong anti-facebook bias
I can tell you from own experience that Facebook's dark patterns are incredibly frustrating at best, and at worst come off as malicious to the end-user.
For example, I refuse to download the Facebook app. When using the mobile website, it often shows me as having new messages. Clicking the notification then redirects me to download the app. Requesting the desktop site, however, shows no notifications and has no redirect.
How am I supposed to trust a company that puts me through that? Is it a bias when they actually lie to me almost daily?
