Yes but No. For most people writing this kind of mail should not be a problem. However, for many different reasons it can become difficult to write such things: This mail is some kind of formal letter and alters a contract. Let’s imagine someone with a learning disability, they may be able to sign up for a online service, as they have done it many times. Writing a formal letter they may not have done many times and they cannot map past experiences the same way as a neurotypical person.

Depending on the local law this may be a reason why forced arbitration has to be opt-in: Typically the law should protect the weaker party. As the barrier for writing this letter is higher than the sign-up process, there is an argument that the chosen opt-out process of discord is targeted against some of their weakest customers.

In short, I don’t write formal documents often in my role as a software engineer.

There are any number of ways that an opt-out message could be too ambiguous to be legally interpreted. For example, if you just send the message saying “no thanks, I don’t want to use arbitration”, but forget to identify yourself in a way that is meaningful to the other party, it may not hold up in any proceedings.

For example, either your legal name or username may be required, or both, depending on whether you need to prove you are/were a user at the time of opt-out.

Specifying the confirmation is helpful as well in a normal document that someone reads.

Several other companies have made opt outs that you have to send paper mail for as a way to raise the barrier of rejection.

People are lazy. I am lazy. I asked a resource to do it for me and shared the results to help others like me. This helps reduce the barrier to people who would like to opt out but can’t be bothered to figure out how to write that email.
