Tangentially related, but I recently spun up a Windows VM and used Edge to search Bing for "Firefox" and this is result I got[1].
It's a giant banner that says, "You're already browsing in Microsoft Edge. Keep using to get world class performance with more privacy, more productivity, and more value."
That banner is followed by another giant banner image telling me to get "Get Robux using Microsoft Edge. Join Microsoft Rewards and use Microsoft Edge. Get a 100 Robux eGift Card on us when you search with Microsoft Bing on Microsoft Edge for 5 days after you join."
I had to scroll to even see the relevant search results for my search term. I'm assuming most non-power users won't scroll because they were just assured that they were "already browsing in Microsoft Edge", which is apparently more private, productive and valuable than what they intended to search for.
Ostensibly this is the exact opposite function one wants out of a search tool, obscuring results. For Microsoft to design such an egregious UX for one of their key platforms, the incentives must be staggering. Calling this a dark pattern doesn’t go far enough, in my opinion. It’s outright user-hostile.
The targeted ad banner is hilarious. It reminds me of that scene in Silicon Valley where Dominos appears in a fantasy medieval universe because Dinesh mentions pizza.
