It's somehow very funny to me that we are talking about data transfer (QUIC) but that what happens at "level 8" of the OSI stack can also be complicated depending on what system level 8 runs.
In other words, if you have this communication protocol, when it reaches level 8 the message might not be delivered or be misinterpreted based on the person. For example in this thread with some people seeing this as racist, some people see it as nothing.
