> Where would you draw the line… what percentage of users would have to dislike amp for you to think it was reasonable to add an option? One easy piece of math is (cost of adding and maintaining that feature) vs. [(users who dislike) x (% of users who would quit you) x (profit per user)] For example, if 10% of all users disliked it (300M users), but only 1% of those would leave your services (3M users) and you made, on average, $10 per user in profit, you'd be putting $30M/year of profit at risk, which is probably enough to hire a few people to build and maintain that feature.
