Wanting people to not die of heat stroke and trying to spread some price of information aren’t exactly the same thing, even if the former leads to the latter.

Still, propaganda usually is reserved for pushing some sort of broader doctrine or political goals, not just trying to get information to people about protecting themselves.

Also propaganda can be good… I’d say a lot of political memes are technically propaganda. Doesn’t mean they’re necessary being deceitful or misleading and can be used as a positive force for spreading anti-ruling class information. Granted, clearly the other personal clearly meant it negatively. Weird that sharing basic medical advice has become politically charged…
