Is it permissible to download a resource that is currently available publicly and freely from the internet without permission from the one who posted it and/or the one who hosts the website?
For example, one can download a YouTube video using third-party software. Eventually the person who uploaded the video may remove the video; this might be because he wants to sell it, because he is embarrassed by it, etc. YouTube may also remove the video if they find it contains copyrighted material or is exceedingly offensive (which we should not download to begin with). It seems that the basic reasons for why a resource may be taken down are either copyright/legal or personal.
Even if there is a general rule of this being forbidden, is there a possibility that this is permissible for Torah resources?
