How did it start? Some people adopted it, then their friends adopted it, etc. How does it stop? The same way!
If people are made aware and meet resistance (e.g., a person they really want to keep in touch with who doesn’t use that app), things change.
A boycott that does not drive the company out of business is not automatically unsuccessful: more people learn about the issue, some stores might start stocking competitor’s goods, etc. In a functioning system, if a bunch of people voted for the loser the winner would feel the pressure to adjust policies (vs. if no one did and the winner feels righteous enacting the extreme version of the policies you disagree with), and if not well next time more people may support the losing party.
Chat programs are not stores in any typical sense of the word.
Chat programs are effectively clubhouses. Convincing a person that they’ve joined the wrong club, invested time and effort in the wrong club, and should make better and more informed choices in clubs…
Lol. Have you MET a human before?
Good luck and don’t hold your breath.
Chat programs are also not clubs. There is no associated identity. No hardcore WhatsAppers it Telegrammers.
In fact, if you regularly meet actual humans, you might find out that most of them simply don’t care.
You dislike WhatsApp? Give them something equally convenient but that cares about privacy and they will just use it. Refuse to add them on WhatsApp and if you are an interesting person they will install whatever you use, even Signal, to stay in touch.
Please keep it polite. I don't see how you can know that commentator's intent.
If enough people join you, it's a win. If not, you've wasted your effort / money / vote / time.
Sometimes it's hard to discern if that critical mass exists.
