Would it be wrong to give my players an ultimatum?

[4]

To keep this brief, I dislike D&D 5e and am not a fan of running it or how it plays. However, I introduced my players to RPGs through D&D and said that I would run a "Part 2" to our campaign, though the first arc was completely self-contained and could be ended here.

I'm considering telling them respectfully that I won't be running another part to the campaign unless it's with a different system. With that said, I already told them I would continue running this campaign in 5e.

I feel bad essentially going back on my word and telling them that if they don't play what I want to run, we won't play.
