Why? It gives the creators more money than watching ads and you get no ads on Smart TVs etc.
I mean yes you can watch youtube with vanced, Sponsorblock etc pretty much without ads everywhere, but because I hate ads and did that I like supporting the channels without having to manage a ton of little donations
I wouldnt call it dumb overall. It definitely has good sides.
For example the karma race aka who posts a news first. That leads to communities being very up to date and discussion can happen very quickly.
Also it creates some incentive to post good comments, because its fun to know people value your opinion
But ofc there is also the other side that people post dumb memes and do reposts.
But acting like it has no worth at all is stupid as well imo
Nato is in war with russia. We train soldier, we send equipment, we give intelligence…If this is not being in a war I dont know…
