I am OK to register, even if I think that a quick demo should be possible without this step.
But I won't register with Google or Facebook or anything except an email.
However, I never thought about the privacy concerns many people have regarding google signins. Thank you for the insight! I will definitely consider a workaround to this.
It is not very convenient to do the same with Google etc.
try creating a new google account: - whoops, you need a phone number - whoops, you need to go through a welcome guide (it's getting progressively harder to skip it) - etc. etc.
All that for trying some use random service some random posted on some random news aggregator website without tying it to your 'main online identity' ............
