I think it also fundamentally changes the conversation. Valid but “unpopular” comments can’t get buried in downvotes. The voting system on Reddit was based on a sane logic that totally neglected to consider how people actually behave… the idea of up and down votes to crowd-source relevance and quality of content makes sense, but all anyone did was use it as an agree / disagree button which broke the idea entirely.
While I don’t disagree, YouTube won’t care. Currently folk like you and I who evade their ads are freeloading. We get all the content and YouTube gets nothing in return. Having those who block ads abandon watching doesn’t lose YouTube anything, and maybe saves them a little bandwidth bill I guess?
