I'm not sure. While I understand that developer time needs to be cut down or restrained sometimes - though perhaps not at Amazon in this case, which concerns their core business -, your example could merely turn out to be a way of losing 1% of the users. Usage statistics alone cannot tell you whether your users hate or like a feature. Some features are always going to be used more than others.

What if that feature costs 30% of dev time? Without being able to measure you wouldn’t be able to make a good judgement. Imagine how science would work without experiments?

Wouldn't focus groups work better AND respect your users?

Devs think it is either telemetry or develop blind but in reality software was developed (and possibly was better) before telemetry using focus groups.
