It's just that customers are more understanding when they see their Netflix not working either otherwise they just think you're less professional. Try talking to customers after an outage and you will see.

It costs a lot of money to move, you don't know if the alternative will be any better, and if it affects a lot of companies then it's nobody's fault. "Nobody ever got fired for buying Cloudflare/AWS" as they say.

it's not just that, it's the creation of a sorta status symbol, or at least of symbol of normality.

there was a point (maybe still) where not having a netflix subscription was seen as 'strange'.

if that's the case in your social circles -- and these kind of social things bother you -- you're not going to cancel the subscription due to bad service until it becomes a socially accepted norm.

For example, Cloudflare employees make money on promises to mitigate such attacks, but then can’t guarantee they will, and take all their customers down at once. It’s a shared pain model.
