Incognito Mode was a mix between a couple suggestions that didn't satisfy the original intent of the "incognito" part of the original suggestion. From my discussions with users, it seems I have not been the only one being left with a sore impression over time.
Benefit of the mode
The original suggestion behind this was to allow a user to hide their online presence to friends in their list. This would allow them to play without having a friend click on their name to join. It allowed a user to take it slow. By having a feature like this, a user would not have to remove their friends to be left alone for a bit.
A different suggestion had asked for Steam players to be able to play as a guest. I suspect this was mixed into the original suggestion. If a player has an account (as they 100% do if they are playing on Steam), then I see no reason for them to need to jump into a guest account; especially given how it results in bad team balance with smurfing.
Its abusive nature
The way it currently works by obfuscating a player's username makes the user feel anonymous. With this feeling comes a higher likelihood of doing things one may otherwise avoid due to peer pressure and reputation. Similar to how guests using the chat was abused leading to its removal, I see users use incognito to be toxic and scummy to others and water down the experience for both myself and others I have spoken with (I obviously can't speak for all). Players have also had difficulty knowing how to handle reports for bad chat behaviour when they can't even tell who the perpetrator is.
It also plays a similar role to those who jump accounts or change names regularly. There's no way to build up any sense of comradery or rivalry with players. There's less sense of community and more feelings of alienation. For someone like myself, I prefer to have a name next to a person I see. I want to know to whom I hold my respects for or avoid based on how disrespectful they may be.
