Uber but for vitrue signalling (*).
(I joke, because other remarks I want to make will get me in trouble).
*: I know this term is very RW coded, but I don't think it is that bad, esp when you mean it like 'an empty gesture with a very low cost that does nothing except for signal that the person is virtuous.' Not actually doing more than a very small minimum should be part of the definition imho. Stuff like selling stickers you are pro some minority group but only 0.05% of each sale goes to a cause actually helping that group. (Or the rich guys charity which employs half his family/friends, or Mr Beast, or the rightwing debate bro threatening a leftwinger with a fight 'for charity' (this also signals their RW virtue to their RW audience (trollin' and fightin')).
Too late im already simulating everybody in this thread in my mind.
