It would be better to give constructive criticism, like:
This is a really cool tool! I might even choose to use it, but I have a few concerns: 1) it sends too much data unfiltered to the algolia search servers. Could you instead make it a button that only then triggers the request or opens another browser window? 2) the analytics are also a concern. In general, you should always make these opt-in; better, ask the user through a dialogue to enable them; even better, request feedback through some other system (github for example).
Let’s try and be nice here and give people the benefit of the doubt.
FWIW, I am taking the privacy and security concerns raised in this thread seriously. In fact, this type of candid feedback is one of the best things about HN. I anticipate it will take me a few days to choose and implement some of the fixes suggested here.
Sharing people's browsing data with third-parties can threaten their lives in some circumstances. There's no excuse for a developer creating browser extensions not to take this threat seriously in 2018. It's negligent.
I get the concern and share it, but your comment only said that what they did was wrong. It didn’t offer any ideas of how to fix it. Telling someone they’re on the wrong road but not telling them how to get to the correct one leaves them just as lost.
And let's all try not to get the users of our software imprisoned or killed: https://boingboing.net/2018/01/28/30000-accused.html
I find it strange how everyone used to be concerned about XSS exploits (including Google themselves who painstakingly implemented reflective XSS prevention, nonce support, and support for XSS-blocking HTTP headers in Chrome) and now they all love XSS as long as it has decent marketing and a clean presentation as an "extension".
