Point taken. However, saying "X app connects to Y app, that's for sure" when that is NOT the case is wrong. Period. Facts are facts.
"We should do X because things are like Y" when things are like Z, you just have to check the code and show it, that's a hard fact.
Maybe I should have said "remembers facts incorrectly" instead of "opinion". Sorry.
Re: having worked in a famous SV company doesn't mean everybody should get a free pass to say B.S., right? I'm sure your FAANG company isn't made of perfect human beings (or has a perfect hiring process).
