Mobile phones could be open systems like PCs are. But they aren't. So we should oppose this movement to use phones for everything until the situation changes.

Not to mention that old people is suffering (at least here in Spain) a lot because services push everyone into apps etc.

I cancelled my fathers bank account for this very reason and moved him to a credit union. It was painful but their customer support was so awful that it was worth it.

The last straw was that they told him he couldn't do a money transfer from his local office but he had to use a mobile app. He called me to help him with that. That got me angry.
