Besides Venmo, another good way to talk to people about financial privacy and censorship is via its motherdeath ship PayPal.
It’s an easy one to bring up in a lot of circumstances.
For example:
Was on a work mtg yesterday and was talking about common payment integration options on calendar services—-casually mentioned I won’t use PayPal.
Why not, someone asked.

Why won't you use paypal?
Debanking and discriminating for one…DuckDuckGo that. Paypal mafia for another. For example long history here(not recent): 

Human rights organisations call out PayPal for its digital discrimination against Palestinians – Middle East Monitor
See here for @Whitney Webb et al articles about PayPal mafia.
