I don't think those are copyright infringement according to the law, however the way the laws are written in many places has effectively made things like picking up background music in your videos illegal. When the only way online platforms can comply with the law is to have automated systems take down anything with copyrighted music in it, fair use largely disappears on those platforms. So I agree that copyright law needs reform, but there are actually pretty good laws surrounding fair use that protect the examples you provided - the problem is that with the current laws it is almost impossible for platforms to preserve fair use while getting rid of copyright infringement.
