Which is also our duty as costumers to stop using services which are scammy and are basically selling your information around, putting you into flagged lists if you deposit the wrong set of bitcoins on it on your name, and so on.
That's fair. Though I'm personally more of informing the user on what they're giving up or risking when using Coinbase so they could decide for themselves if they want to continue on, as opposed to just telling people to not use it at all.
It is really insane that anyone would be using Coinbase in 2019. There's no point.
The thing is, I'm pretty sure we aren't the target audience of Coinbase. They're targetting those people who just saw a Coinbase advertisement then simply buy bitcoins through the advertised link; basically the people who aren't fond of doing research.
They refuse to answer about many pressing questions.
Unfortunately they can simply just not answer it just because they don't want to. Businesses that really aren't transparent is very common especially for those with a huge monopoly on certain niches (e.g. Google, Facebook, etc).
