This is to some extent a false dichotomy. Generally speaking, products that prioritize fixing a problem “above” making money do not exist. There are no alternatives. Businesses can’t sustain that. Sometimes it happens for a short while, and eventually they reduce the level of service, or charge more money, or die.

I don’t know why you’re picking on startups. Big companies are where you see enshittification the most, and it’s because economies of scale require them to cut costs. Startups can often use VC fuel to offer delightful and unprofitably superior solutions to problems. That goes away after startups graduate to being real companies.
