You can’t look at switching costs in a vacuum. The real metric is the Expected Return. When the original app is going to remain open, there is a very high risk that, ultimately, most of the users you care about aren’t going to make the switch. Even if the switching costs are low, the ER is negative because the most likely outcome is that you waste your time trying to migrate to a new platform that doesn’t really take off.
When the original app might stop existing then the calculus switches and even a high cost option is worth it because the odds are much higher that your efforts will pay off.
Even if they are legitimately pissed-- ignore them. Fusing the singular and plural second person pronouns was a mistake and “y’all” has come to deliver us from misery and confusion.
