I find calendly depersonalizing and extremely insulting. I.e. the shift of power when someone says "Hey, let's find a time to chat" and the answer is "Here is my calendly link, good luck". I usually break off the conversation there.
while i agree that saving time is a worthwhile goal, i can sympathise with the unhappiness over beeing deferred to an (online) form for stuff that could be tackeld here and now.
Breaking the conversation at the point, where you are being offered to pick a convenient time looks like a good question for AITA on Reddit.
