I don’t think people want to vote for a party. People want to vote for someone who’s making sense for them, and looks like for majority it was Trump this time.
An “actual left wing party” must not only have ideology, but a sound plan on how to improve people’s lives and an ability to communicate this plan to people, loud and clear. Actually, as populists are now trusted everywhere in the world, the plan is less important than communication
Apple does extensive audit of mobile apps, including limitations of tracking. So the app cannot spy on something you are not letting it to know. But you are giving it a bunch of info voluntarily.
I’d say using that app on iOS is similar to making a food delivery order using a loyalty member ID. Basically, you are letting the company (McDonald’s) know who you are, what is your phone number, where do you live, and what do you like to eat. And if they wish to, they could use all that to purchase your profile from a data brocker. Or they can sell that info for a few cents to make up on that discount.
