This doesn’t make sense. Whether they sit out or vote 3rd party doesn’t matter. The strategic reason for GOP financiers supporting a 3rd party candidate is to draw votes away from their opponent. A sit-out or a vote for 3rd party achieves the same thing.
Encouraging people to sit out is just encouraging people to disengage from the entire process, which will enforce a trend that helps GOP candidates.
Take a slice of white bread and a single slice of American cheese. Microwave just long enough to make the cheese slightly burn… the phase just after bubbly will get harder when it cools. Top with hot sauce or spicy ketchup… but not too much. If you can find it, there is an Indian curry spruced ketchup that is awesome.
