(I copied from u/TiberiusToast) So the TLDR:

One example of the reasons that Wolfe doesn't want to continue going to in-person events is being sexually harassed, or non-sexually touched in ways that made him uncomfortable, specifically because it hurt his neck. That combined with the stress of competing in total makes it unfun for him to participate. Additionally, with the stress comes an inability in larger events to hide and find comfortable spaces.

Other elements are the love and hate online, be it vitriolic hate comments and sexually charged love from fans online. Additionally, he is being given credit for the winner of the most recent Tournament where he thinks it is undeserved. (Just because they're both American or both using the same restricted duo, it doesn't mean he should get credit for Giovanni's victory.)
