Sure, they'll be more predictive that way, and simultaneously it's valuable to not piss off your customers.
In that case I would take them out of the experiment and impute the censored data.

Ah, that makes way more sense.
This is more true for larger flags that substantially change the experience and may not implement niche or edge-case functionality. Obviously you want to avoid these kinds of tests if possible but it’s not always possible.
