I find the idea that you shouldn't point out hypocrisy because it might trigger divisiveness, divisive. It stinks of a desire to shut down debate because it's not going the way you want.
What's your goal? What do you actually want to accomplish in the end? I'm asking in all seriousness. And following up, how do you plan to accomplish that goal?
In the case of working for user data privacy, we're working against companies that are benefiting from the data they collect and their lobbyists, as well as people who aren't aware of the situation and often only see the benefits of the apps they're using. And those people cross many demographic and political lines. I don't think user privacy is a partisan issue. It's going to be an uphill battle. You think pointing out all of the differences and disagreements of those who don't agree with you, all of the inconsistencies you see in their positions is going to help? I sincerely don't think so.
The point isn't that pointing out hypocrisy is wrong, it's that it gets in the way of your goals.
If it's more important to you to point out those inconsistencies than improve the user privacy situation, I think you have your priorities wrong. If you think you can only remedy the user privacy situation by first correcting their inconsistencies, I think that's wrong-headed and doomed to failure on both counts. But you're certainly entitled to your opinion and free to disregard mine.
