This is an intensely user hostile view point, ironically enough. "The dark patterns being foisted upon the average user are their own fault, they deserve what they get"
In fact, I think this attitude is how the developers and product managers responsible for this stuff sleep at night, "these people deserve this for their moral failings, so what I'm doing doesn't make me a terrible person"
How would my mom switch from her crappy bank app? That app that the bank is kind of forcing her to use by making the in person experience so terrible and, well, because of COVID. There is only one bank in her town, I guess she could start driving "to the city" for banking but, surprise, all those banks have equally shitty apps.
She could switch from Facebook to ... what exactly? Her extended family are all on Facebook, her grandkids are posting pics of the great grandkids on Facebook. Yeah, she deserves the disaster that is Facebook.
