So would it be
"On the allegedly, Jack rage quit."

Stylistically, I think it depends more on the writer. That works, however I might
wright it: "...On the contrary,
Jack allegedly rage quit..." and
through in a final
gerund (or whatever you call that last comma separated statement) I might add; ".., Nautical Shore."
Or I might write an entire paragraph expanding and developing the "
contrary" idea and throw in a "...
Jack allegedly quit in a rage..." statement/phrase with the words "...obnoxious, dull and
faux contrarian..." as descriptors elsewhere.
I also enjoy the employment of literal (as well as
literary) imagery, which in this instance would lend itself to quite an "egg-headed" joke at
JaxTard's expense. For instance, I could
contrast the following image:

with the his lack of skillz {

There are myriad ways to disguise, encode and otherwise lead astray the less astute among your readership. Done carefully, everyone has a laugh and only your actual target audience member(s) get the Real Joke.
As it were... I have said two mucks!
Apogees.
In short, the example you provided was perfectly sufficient and even terse when compared to my drivel above.
