If the problem with Sushi partnership is that it is unbalanced, then why not have the Partnership Team discuss with them and come to a more balanced relationship. Now that Olympus is established in the DeFi space, we have more clout and leverage to push for a more "Special/Preferred Partner" status.
Putting effort into that would be easier than the alternative. This will allow us to address one of the major complaints vs. Sushi and afford us time exploring a safer alternatives. If Sushi are not willing to entertain this, then sure, we can discuss the option of the DEX. We owe them at least the chance to respond. More honorable approach.
Adding to this, the use of the community name "Ohmie" in the swap title, not a fan of this approach… if it is 100% operated and controlled by the DAO possibly, even then I would look for a better name.
Finally, I do commend ChefOmi's attitude and friendly/calm approach in addressing the concerns and not getting defensive or agitated in their response. That is a positive.
