I think you misunderstood what they are trying to convey.
Yes, it’s quick and easy to install (privacy respecting alternative). But to even get to the point that you recognize that you need that alternative is a time commitment as well. They are so busy trying to stay alive and support themselves that they don’t have the extra mental registers to devote to keeping up with privacy implications of popular software.
Not to mention, some software now suffers from IE6-itis, except this time with chromium. So if a user encounters one of those issues on an important site, they’re more likely to drift over to the chromium side again. That friction alone causes more hardship for a person in their situation than simply giving up some privacy for convenience.
They’re also not even making excuses. They’re simply telling you what the point of view is in their world.
Your current approach presents a holler-than-thou attitude that is rude and off-putting. Ultimately, it’s not your job nor mine to chastise them for their choices. If they’re reading this thread, that shows interest in the topic.
Allow them to discover it for themselves (with guided encouragement and assistance if requested) instead of being guilted into a decision. That will have a much more long-lasting impact.
I see the method you attempt all over the Internet, and it always has the same effect of contributing to a toxic, elitist culture. IMHO, that needs to stop if we have any chance of changing more minds to be privacy-aware.
You got it! We all need a little reminder to take context into account sometimes. And I do appreciate what you were trying to do, which is promote privacy. It’s a laudable goal, and one that I encourage you to continue. Just remember to meet people where they are, instead of where you want them to be. ;)
